	Principal Activities
	China BAK Battery, Inc. (“China BAK”) is a corporation formed in the State of Nevada on October 4, 1999 as Medina Copy, Inc. The Company changed its name to Medina Coffee, Inc. on October 6, 1999 and subsequently changed its name to China BAK Battery, Inc. on February 14, 2005. China BAK and its subsidiaries (hereinafter, collectively referred to as the “Company”) are principally engaged in the manufacture, commercialization and distribution of a wide variety of standard and customized lithium ion (known as "Li-ion" or "Li-ion cell") rechargeable batteries for use in cellular telephones, as well as various other portable electronic applications, including high-power handset telephones, laptop computers, power tools, digital cameras, video camcorders, MP3 players, electric bicycles, hybrid/electric motors, and general industrial applications.
	The shares of the Company traded in the over-the-counter market through the Over-the-Counter Bulletin Board from 2005 until May 31, 2006, when the Company obtained approval to list its common stock on The NASDAQ Global Market, and trading commenced that same date under the symbol "CBAK".
	Basis of Presentation and Organization
	As of September 30, 2013, the Company's subsidiaries consisted of: i) BAK International Limited (“BAK International”), a wholly owned limited liability company incorporated in Hong Kong on December 29, 2003 as BATCO International Limited, which changed its name to BAK International Limited on November 3, 2004; ii) Shenzhen BAK Battery Co., Ltd. (“Shenzhen BAK”), a wholly owned limited liability company established on August 3, 2001 in the People's Republic of China (“PRC”); iii) China BAK Asia Holdings Limited, a wholly owned limited liability company incorporated in Hong Kong on July 9, 2013; iv) BAK Battery (Shenzhen) Co., Ltd.

(“BAK Canada”), a wholly owned limited liability company established on December 20, 2006 in Canada as BAK Canada Battery Ltd., which changed its name to BAK Battery Canada Ltd. on December 22, 2006. The Company decided to dissolve BAK Canada due to the financial difficulties and filed for bankruptcy on March 28, 2013. As of September 30, 2013, BAK Canada still has not yet been dissolved; viii) BAK Europe GmbH (“BAK Europe”), a wholly owned limited liability company established in Germany on November 28, 2007; and ix) BAK Telecom India Private Limited (“BAK India”), a wholly owned limited liability company established in India on August 14, 2008. As of September 30, 2013, BAK International beneficially owns 100% of BAK India partly through a nominee agreement with one of its employees.
	BAK Tianjin was established in Tianjin Technology Industrial District on December 12, 2006 as a wholly owned subsidiary of BAK International with registered capital of $99,990,000. Pursuant to BAK Tianjin's articles of association and relevant PRC regulations, BAK International was required to contribute $20,000,000 to BAK Tianjin as capital (representing 20% of BAK Tianjin's registered capital) before March 11, 2007. An extension from the Business Administration Bureau of Beichen District, Tianjin, was obtained to make this contribution no later than December 11, 2007. On November 16, 2007, BAK International contributed approximately $20,000,000 capital to BAK Tianjin. The remaining $79,990,000 was originally required to be fully contributed no later than December 11, 2008 and an extension from the Business Administration Bureau of Beichen District, Tianjin, was obtained to make this contribution no later than December 11, 2009. On November 16, 2009, BAK International contributed approximately $9,000,000 capital to BAK Tianjin and as of November 16, 2009, the total contribution from BAK International was $29,000,000. The remaining $70,990,000 was originally required to be fully contributed no later than December 11, 2009 and an extension from the Business Administration Bureau of Beichen District, Tianjin, was obtained to make this contribution no later than December 2012. In August 2011, BAK International contributed approximately $21,000,000 capital to BAK Tianjin and as of September 30, 2011 and September 30, 2012, the total contribution from BAK International was $50,000,000. On September 17, 2012, BAK Tianjin issued an application with respect to the decrease of capital from $99,990,000 to $50,000,000. On November 27, 2012 the Business Administration Bureau of Beichen District, Tianjin, approved the request of BAK Tianjin's capital reduction. According to the approval, the BAK Tianjin's aggregate investment still remains at $99,990,000 while the registered capital was reduced to $50,000,000. BAK Tianjin is principally engaged in the manufacture of larger lithium ion batteries for use in cordless power tools and various types of vehicles. The Company intends to move all the BAK Tianjin assets except for land use rights and buildings to BAK Dalian in fiscal year 2014.
	Prior to July 12, 2013, the Company beneficially owned 100% of Tianjin Meicai New Materials Technology Co., Ltd., which was incorporated in the PRC on February 22, 2011. On July 12, 2013, the Company entered into an equity transfer agreement with Tianjin Zhantuo International Trading Co., Ltd., an unrelated party, for the disposal of its 100% equity interest in Tianjin Meicai for a consideration of $29.3 million. The disposal of Tianjin Meicai was completed on August 27, 2013 (Note 8).
	On November 6, 2004, BAK International, a non-operating holding company that had substantially the same shareholders as Shenzhen BAK, entered into a share swap transaction with the shareholders of Shenzhen BAK for the purpose of the subsequent reverse acquisition of the Company as described below. Pursuant to the terms of the share swap transaction, BAK International acquired all of the outstanding shares of Shenzhen BAK for $11.5 million in cash, while the shareholders of Shenzhen BAK acquired substantially all of the outstanding shares of BAK International for $11.5 million in cash. As a result, Shenzhen BAK became a wholly-owned subsidiary of BAK International. After the share swap transaction was completed, there were 31,225,642 shares of BAK International stock outstanding, exactly the same as the number of shares of capital stock of Shenzhen BAK that had been outstanding immediately prior to the share swap, and the shareholders of BAK International were substantially the same as the shareholders of Shenzhen BAK prior to the share swap. Consequently, the share swap transaction between BAK International and the shareholders of Shenzhen BAK was accounted for as a reverse acquisition of Shenzhen BAK with no adjustment to the historical basis of the assets and liabilities of Shenzhen BAK.
	On January 20, 2005, the Company completed a share swap transaction with the shareholders of BAK International. The share swap transaction, also referred to as the “reverse acquisition” of the Company, was consummated under Nevada law pursuant to the terms of a Securities Exchange Agreement entered by and among China BAK, BAK International and the shareholders of BAK International on January 20, 2005. Pursuant to the Securities Exchange Agreement, the Company issued 7,965,215 shares of common stock, par value $0.001 per share, to the shareholders of BAK International (including 6,245,128 shares to the original shareholders and 1,720,087 shares to new investors who had purchased shares in the private placement described below), representing approximately 97.2% of the Company's post-exchange issued and outstanding common stock, in exchange for 100% of the outstanding capital stock of BAK International.
	The share swap transaction has been accounted for as a capital-raising transaction of the Company whereby the historical financial statements and operations of Shenzhen BAK are consolidated using historical carrying amounts. The 1,152,458 shares of China BAK outstanding prior to the stock exchange transaction were accounted for at the net book value at the time of the transaction, which was a deficit of $1,672.
	Also on January 20, 2005, immediately prior to consummating the share swap transaction, BAK International executed a private placement of its common stock with unrelated investors whereby it issued an aggregate of 1,720,087 shares of common stock for gross proceeds of $17,000,000. In conjunction with this financing, Mr. Xiangqian Li, the Chairman and Chief Executive Officer of the Company, agreed to place 435,910 shares of the Company's common stock owned by him into an escrow account pursuant to an Escrow Agreement dated January 20, 2005 (the “Escrow Agreement”). Pursuant to the Escrow Agreement, 50% of the escrowed shares were to be released to the investors in the private placement if audited net income of the Company for the fiscal year ended September 30, 2005 was not at least $12,000,000, and the remaining 50% was to be released to investors in the private placement if audited net income of the Company for the fiscal year ended September 30, 2006 was not at least $27,000,000. If the audited net income of the Company for the fiscal years ended September 30, 2005 and 2006 reached the above-mentioned targets, the 435,910 shares would be released to Mr. Xiangqian Li in the amount of 50% upon reaching the 2005 target and the remaining 50% upon reaching the 2006 target.
	Under accounting principles generally accepted in the United States of America (“US GAAP”), escrow agreements such as the one established by Mr. Xiangqian Li generally constitute compensation if, following attainment of a performance threshold, shares are returned to a company officer. The Company determined that without consideration of the compensation charge, the performance thresholds for the year ended September 30, 2005 would be achieved. However, after consideration of a related compensation charge, the Company determined that such thresholds would not have been achieved. The Company also determined that, even without consideration of a compensation charge, the performance thresholds for the year ended September 30, 2006 would not be achieved.
	While the 217,955 escrow shares relating to the 2005 performance threshold were previously released to Mr. Xiangqian Li, Mr. Xiangqian Li executed a further undertaking on August 21, 2006 to return those shares to the escrow agent for the distribution to the relevant investors. However, such shares were not returned to the escrow agent, but, pursuant to a Delivery of Make Good Shares, Settlement and Release Agreement between the Company, BAK International and Mr. Li entered into on October 22, 2007 (the “Li Settlement Agreement”), such shares were ultimately delivered to the Company as described below. Because the Company failed to satisfy the performance threshold for the fiscal year ended September 30, 2006, the remaining 217,955 escrow shares relating to the fiscal year 2006 performance threshold were released to the relevant investors. As Mr. Li has not retained any of the shares placed into escrow, and as the investors party to the Escrow Agreement are only shareholders of the Company and do not have and are not expected to have any other relationship to the Company, the Company has not recorded a compensation charge for the years ended September 30, 2005 and 2006.
	At the time the escrow shares relating to the 2006 performance threshold were transferred to the investors in fiscal year 2007, the Company should have recognized a credit to donated shares and a debit to additional paid-in capital, both of which are elements of shareholders' equity. This entry is not material because total ordinary shares issued and outstanding, total shareholders' equity and total assets do not change; nor is there any impact on income or earnings per share. Therefore, previously filed consolidated financial statements for the fiscal year ended September 30, 2007 will not be restated. This share transfer has been reflected in these financial statements by reclassifying the balances of certain items as of October 1, 2007. The balances of donated shares and additional paid-in capital as of October 1, 2007 were credited and debited by $7,955,358 respectively, as set out in the consolidated statements of changes in shareholders' equity.
	In November 2007, Mr. Xiangqian Li delivered the 217,955 shares related to the 2005 performance threshold to BAK International pursuant to the Li Settlement Agreement; BAK International in turn delivered the shares to the Company. Such shares (other than those issued to investors pursuant to the 2008 Settlement Agreements, as described below) are now held by the Company. Upon receipt of these shares, the Company and BAK International released all claims and causes of action against Mr. Xiangqian Li regarding the shares, and Mr. Xiangqian Li released all claims and causes of action against the Company and BAK International regarding the shares. Under the terms of the Li Settlement Agreement, the Company commenced negotiations with the investors who participated in the Company's January 2005 private placement in order to achieve a complete settlement of BAK International's obligations (and the Company's obligations to the extent it has any) under the applicable agreements with such investors.
	Beginning on March 13, 2008, the Company entered into settlement agreements (the “2008 Settlement Agreements”) with certain investors in the January 2005 private placement. Since the other investors have never submitted any claims regarding this matter, the Company did not reach any settlement with them.
	Pursuant to the 2008 Settlement Agreements, the Company and the settling investors have agreed, without any admission of liability, to a settlement and mutual release from all claims relating to the January 2005 private placement, including all claims relating to the escrow shares related to the 2005 performance threshold that had been placed into escrow by Mr. Xiangqian Li, as well as all claims, including claims for liquidated damages relating to registration rights granted in connection with the January 2005 private placement. Under the 2008 Settlement Agreement, the Company has made settlement payments to each of the settling investors of the number of shares of the Company's common stock equivalent to 50% of the number of the escrow shares related to the 2005 performance threshold these investors had claimed; aggregate settlement payments as of March 31, 2013 amounted to 73,749 shares. Share payments to date have been made in reliance upon the exemptions from registration provided by Section 4(2) and/or other applicable provisions of the Securities Act of 1933, as amended. In accordance with the 2008 Settlement Agreements, the Company filed a registration statement covering the resale of such shares which was declared effective by the SEC on June 26, 2008.
	Pursuant to the Li Settlement Agreement, the 2008 Settlement Agreements and upon the release of the 217,955 escrow shares relating to the fiscal year 2006 performance threshold to the relevant investors, neither Mr. Li or the Company have any obligations to the investors who participated in the Company's January 2005 private placement relating to the escrow shares.
	As of September 30, 2013, the Company had not received and claim from the other investors who have not been covered by the “2008 Settlement Agreements” in the January 2005 private placement.
	As the Company has transferred the 217,955 shares related to the 2006 performance threshold to the relevant investors in fiscal year 2007 and 73,749 shares relating to the 2005 performance threshold to the investors who had entered the “2008 Settlement Agreements” with the Company in fiscal year 2008, pursuant to “Li Settlement Agreement” and “2008 Settlement Agreements”, neither Mr. Li nor the Company has not had any remaining obligations to those related investors who participated in the Company's January 2005 private placement relating to the escrow shares.
	On October 26, 2012, the Company effected a 1 -for- 5 reverse stock split of its issued and outstanding shares of common stock and a proportional reduction of its authorized shares of common stock. All common share and per share amounts, and exercise prices of common stock options disclosed herein and in the accompanying consolidated financial statements have been retroactively restated to reflect the reverse stock split.
	The Company's consolidated financial statements have been prepared under accounting principles generally accepted in the United States of America (“US GAAP”).
	The preparation of financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates. This basis of accounting differs in certain material respects from that used for the preparation of the books of account of the Company's principal subsidiaries, which are prepared in accordance with the accounting principles and the relevant financial regulations applicable to enterprises with limited liabilities established in the PRC, Hong Kong, India, Canada or Germany, The accompanying consolidated financial statements reflect necessary adjustments not recorded in the books of account of the Company's subsidiaries to present them in conformity with US GAAP.
	The Company has net liabilities, a working capital deficiency, accumulated deficit from recurring net losses incurred for the current and prior years and significant short-term debt obligations maturing in less than one year as of September 30, 2013. The Company has been suffering severe cash flow deficiencies. The Company defaulted on repayment of loans from Bank of China. Upon request of Bank of China, Shenzhen Municipal Intermediate Court has ordered to freeze all of the Company's properties in Shenzhen BAK Industrial Park and Tianjin Industrial Park Zone near the end of fiscal year 2013 whereby the Company could not transfer these assets or pledge these assets for any other borrowings. In order to extend the bank loans to various due dates until May 2014, the Company was required to pledge 100% equity of Shenzhen BAK and almost all of its assets in Shenzhen and Tianjin, including land use rights and property rights, equipment, accounts receivable and inventories. As of September 30, 2013, the Company had access to $163.5 million in short-term credit facilities and $29.2 million in other lines of credit as of September 30, 2013, all of which were utilized to the extent of short-term bank loans of $151.4 million and bills payable of $41.4 million. These factors raise substantial doubts about the Company's ability to continue as a going concern
	The Company intends to sell part of its low efficiency assets and appreciating land and properties to repay its short term debts and to provide cash for the development of more promising products such as high power batteries and electric vehicle batteries. The Company transferred its 100% equity interest in Tianjin Meicai to an unrelated party on August 27, 2013. The Company also has intentions to sell its 100% equity interest in BAK International and its subsidiaries (including all their assets and liabilities), and the properties in Tianjin. The Company is in negotiation with the potential buyers about contract terms and clauses. The disposals of these assets require statutory review and approval and the approval by its shareholders. Prior to the completion of these disposals, the potential buyers preliminarily agreed in November and December 2013 that they would lend sufficient money to the Company to help the Company repay past due and maturing bank loans, on the condition that the Company makes certain pledges and guarantees, including its 100% equity in BAK International. Up to the date of these financial statements, the Company had received these loans in the amount of $93.2 million (RMB570 million), renewed short term bank loan of $11.6 million (RMB71 million), repaid bank loans of $94.9 million (RMB580.9 million) and bills payable of $8.1 million (RMB49.2 million). The Company expects the disposals of its 100% equity interest in BAK International and its subsidiaries, and the properties in Tianjin, to be completed by the end of March 2014.
	After the disposal of these assets, the Company will retain BAK Asia and its subsidiary, BAK Dalian. It is the Company's understanding that the Dalian government will grant certain government subsidies to it, including but not limited to land use rights at a favorable price. As of September 30, 2013, the Company received an advance of $24.5 million (RMB150 million) from the Management Committee of Dalian Economic Zone, to finance the Company's removal of operating assets from Tianjin to Dalian. The Company intends to build a new manufacturing site in Dalian with all the operating assets, primarily machinery and equipment, moved from BAK Tianjin, while retaining its customers, employees, patents and technologies. BAK Dalian will focus on the new energy high power battery business, for use in electric vehicle, light electric vehicles and other high power applications. The Company believes with the significant reduction of liabilities and disposal of traditional low margin battery business, it can continue as a going concern and return to profitability.
	It is expected that after the restructuring mentioned above, China BAK will continue to be a US listing company with a low level of liabilities.
	The accompanying consolidated financial statements have been prepared assuming the Company will continue to operate as a going concern, which contemplates the realization of assets and the settlement of liabilities in the normal course of business. The consolidated financial statements do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classification of liabilities that may result from the outcome of this uncertainty related to the Company's ability to continue as a going concern.
	Reclassifications
	Certain amounts included in the 2012 financial statements have been reclassified to conform to the 2013 financial statement presentation as follows:
	(a)	Amortization of prepaid land use rights within one year of $740,276 was erroneously classified in long-term prepaid land use rights in the Company's consolidated balance sheet as of September 30, 2012. The Company has reclassified such as current assets.
	(b)	In presenting the 2012 consolidated balance sheet, value added taxes recoverable of $4,435,143 was erroneously offset against accrued expenses and other payables. The Company has reclassified this as prepayments and other receivables.
	As a result of reclassifications (a)-(b), the amount of the current assets of September 30, 2012 has changed from $169,322,840 to $174,498,259, and the amount of the current liabilities as of September 30, 2012 has changed from $321,087,227 to $325,522,370.
	(c)	In presenting the 2012 consolidated statement of income in prior year, government grant income was presented separately after operating loss. For those grants directly related to the Company's operations, the Company has reclassified and included them in the computation of operating income. Subsidies related for research and development activities and lease prepayments were credited against the related expenses when received. As such, government grants of $3,911,072 related to 2012 research and development activities were offset against research and development expenses, and $247,921 and $4,549 in relation to amortization on subsidies for lease prepayments were offset against general and administrative expenses and research and development expenses, respectively.
	(d)	Given the magnitude of provision for bad debts of $22,634,713, it was separately presented on the face of income statement, instead of presented as part of general and administrative expenses of $22,505,322 and other expenses of $129,391.
	(e)	In presenting the 2012 consolidated statement of income, early settlement discounts granted to customers of $152,336 were included as finance costs. The Company has reclassified these discounts as a reduction of revenue.
	(f)	In presenting the 2012 consolidated statement of income, bank charges of $209,334 were included as finance costs. The Company has reclassified these charges as general and administrative expenses.
	(g)	In presenting the 2012 consolidated statement of income, the land use rights amortization expense in relation to the Company's production facilities of $102,685 was included as general and administrative expenses. The Company has reclassified these expenses as cost of revenues.
	(h)	In presenting the 2012 consolidated statement of income, amounts paid to customers to compensate for unsatisfactory service performance of $459,372 and paid to suppliers on disputed amounts of $236,076 were included as other income (expense). The Company has reclassified these operations related expenses as general and administrative expenses.
	As a result of reclassifications (c)-(h), for the year ended September 30, 2012:
	-	Net revenues have changed from $205,670,946 to $205,518,610 ;
	-	Cost of revenues have changed from $204,197,751 to $204,300,436 ;
	-	Research and development expenses have changed from $5,759,072 to $1,843,451 ;
	-	General and administrative expenses have changed from $40,008,940 to $40,692,507, including a provision for bad debts of $22,634,713 ;
	-	Finance costs, net have changed from $11,265,990 to $10,904,320 ;
	-	Government grant income has changed from $5,353,554 to $1,190,012 ; and
	-	Other expense has changed from $798,528 to other income of $26,311.
	(i)	The change in pledged deposits was classified into cash flows from financing activities in the Company's consolidated statement of cash flows for the year ended September 30, 2012. The Company has reclassified these amounts as components of cash flows from investing activities. As a result of such reclassification, net cash used in investing activities for the year ended September 30, 2012 has changed from $20,450,261 to $20,147,709, and net cash used in financing activities has changed from $455,460 to $758,012.
	(j)	The amounts of write-down of inventories and change in inventories have been reclassified in the presentation of the consolidated statement of cash flows for the year ended September 30, 2012. This restatement has no impact on net cash provided by operating activities.
	(k)	The amounts of provision of doubtful debts and change in trade accounts receivable have been reclassified in the presentation of the consolidated statement of cash flows for the year ended September 30, 2012. This reclassification has no impact on net cash provided by operating activities.

Summary of Significant Accounting Policies and Practices [Text Block]	'
	2.          Summary of Significant Accounting Policies and Practices
	(a)	Principles of Consolidation
		The consolidated financial statements include the financial statements of the Company and its subsidiaries. All significant inter-company balances and transactions have been eliminated prior to consolidation.
	(b)	Cash and Cash Equivalents
		Cash consists of cash on hand and in banks excluding pledged deposits. The Company considers all highly liquid debt instruments, with initial terms of less than three months to be cash equivalents. As of September 30, 2012 and 2013, there were no cash equivalents.
	(c)	Trade Accounts Receivable
		Trade accounts receivable are recorded at the invoiced amount, net of allowances for doubtful accounts and sales returns. The allowance for doubtful accounts is the Company's best estimate of the amount of probable credit losses in the Company's existing trade accounts receivable. The Company determines the allowance based on historical write-off experience, customer specific facts and economic conditions. Bad debt expense is included in general and administrative expenses.
		Outstanding accounts receivable balances are reviewed individually for collectability. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote.
	(d)	Inventories
		Inventories are stated at the lower of cost or market. The cost of inventories is determined using the weighted average cost method, and includes expenditures incurred in acquiring the inventories and bringing them to their existing location and condition. In case of finished goods and work in progress, the cost includes an appropriate share of production overhead based on normal operating capacity.
		The Company regularly reviews the cost of inventories against their estimated fair market value and records a lower of cost or market write-down for inventories that have costs in their excess of estimated market value.
	(e)	Property, Plant and Equipment
		Property, plant and equipment (except construction in progress) are stated at cost less accumulated depreciation and impairment charges. Depreciation is calculated based on the straight-line method (after taking into account their respective estimated residual values) over the estimated useful lives of the assets as follows:
	Buildings	30 - 40 years
	Machinery and equipment	5 - 12 years
	Office equipment	5 years
	Motor vehicles	5 - 8 years
	The cost and accumulated depreciation of property, plant and equipment sold are removed from the consolidated balance sheets and resulting gains or losses are recognized in the consolidated statements of operations and comprehensive loss.
	Construction in progress mainly represents expenditures in respect of the Company's corporate campus, including offices, factories and staff dormitories, under construction. All direct costs relating to the acquisition or construction of the Company's corporate campus and equipment, including interest charges on borrowings, are capitalized as construction in progress. No depreciation is provided in respect of construction in progress.
	A long-lived asset to be disposed of by abandonment continues to be classified as held and used until it is disposed of.
	(f)	Prepaid Land Use Rights
		Land use rights are carried at cost and amortized on a straight-line basis over the period of rights of 50 years.
	(g)	Foreign Currency Transactions and Translation
		The reporting currency of the Company is the United States dollar (“US dollar”). The financial records of the Company's PRC operating subsidiaries are maintained in their local currency, the Renminbi (“RMB”), which is the functional currency. The financial records of the Company's subsidiaries established in other countries are maintained in their local currencies. Assets and liabilities of the subsidiaries are translated into the reporting currency at the exchange rates at the balance sheet date, equity accounts are translated at historical exchange rates, and income and expenses items are translated using the average rate for the period. The translation adjustments are recorded in accumulated other comprehensive income under shareholders' equity.
		Monetary assets and liabilities denominated in currencies other than the applicable functional currencies are translated into the functional currencies at the prevailing rates of exchange at the balance sheet date. Nonmonetary assets and liabilities are re-measured into the applicable functional currencies at historical exchange rates. Transactions in currencies other than the applicable functional currencies during the period are converted into the functional currencies at the applicable rates of exchange prevailing at the transaction dates. Transaction gains and losses are recognized in the consolidated statements of operations and comprehensive loss.
		RMB is not a fully convertible currency. All foreign exchange transactions involving RMB must take place either through the People's Bank of China (the “PBOC”) or other institutions authorized to buy and sell foreign exchange. The exchange rates adopted for the foreign exchange transactions are the rates of exchange quoted by the PBOC, which are determined largely by supply and demand. Translation of amounts from RMB into US dollars has been made at the following exchange rates for the respective years:
		30-Sep-13
		Balance sheet, except for equity accounts	RMB6.1211 to US$1.00
		Income statement and cash flows	RMB6.1894 to US$1.00
		30-Sep-12
		Balance sheet	RMB6.2857 to US$1.00
		Income statement and cash flows	RMB6.3374 to US$1.00
	(h)	Intangible Assets
		Intangible assets are stated in the balance sheet at cost less accumulated amortization and impairment, if any. The costs of the intangible assets are amortized on a straight-line basis over their estimated useful lives. The respective amortization periods for the intangible assets are as follows:
		Trademarks	10 years
		Technology	7 - 10 years
		Computer software	3 - 10 years
	(i)	Impairment of Long-lived Assets
		Long-lived assets, which include property, plant and equipment, prepaid land use rights and intangible assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable.
		Recoverability of long-lived assets to be held and used is measured by a comparison of the carrying amount of an asset to the estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated undiscounted future cash flows, an impairment charge is recognized by the amount by which the carrying amount of the asset exceeds the fair value of the asset.
	(j)	Revenue Recognition
		The Company recognizes revenue on product sales when products are delivered and the customer takes ownership and assumes risk of loss, collection of the relevant receivable is probable, persuasive evidence of an arrangement exists and the sales price is fixed or determinable.
		Net sales of products represent the invoiced value of goods sold, net of value added taxes (“VAT”), sales returns, trade discounts and allowances. The Company is subject to VAT which is levied on the majority of the products of Shenzhen BAK, BAK Electronics and BAK Tianjin at the rate of 17% on the invoiced value of sales. Output VAT is borne by customers in addition to the invoiced value of sales and input VAT is borne by the Company in addition to the invoiced value of purchases to the extent not refunded for export sales. Provision for sales returns are recorded as a reduction of revenue in the same period that revenue is recognized. The provision for sales returns, which is based on historical sales returns data, is the Company's best estimate of the amount of goods that will be returned from its customers.
	(k)	Cost of Revenues
		Cost of revenues consists primarily of material costs, employee compensation, depreciation and related expenses, which are directly attributable to the production of products. Write-down of inventories to lower of cost or market is also recorded in cost of revenues.
	(l)	Income Taxes
		Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carry-forwards. Deferred tax assets are reduced by a valuation allowance to the extent management concludes it is more likely than not that the assets will not be realized. Deferred tax assets and liabilities are measured using enacted tax rates applied to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the statement of operations and comprehensive loss in the period that includes the enactment date.
		The impact of an uncertain income tax positions on the income tax return must be recognized at the largest amount that is more-likely-than not to be sustained upon audit by the relevant tax authority. An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained. Interest and penalties on income taxes will be classified as a component of the provisions for income taxes.
	(m)	Research and Development and Advertising Expenses
		Research and development and advertising expenses are expensed as incurred. Research and development expenses consist primarily of remuneration for research and development staff, depreciation and maintenance expenses of research and development equipment and material costs for research and development. Advertising expenses, including in sales and marketing expenses, amounted to $236,145 and $1,392 for the years ended September 30, 2012 and 2013, respectively.
	(n)	Bills Payable
		Bills payable represent bills issued by financial institutions to the Company's vendors. The Company's vendors receive payments from the financial institutions directly upon maturity of the bills and the Company is obliged to repay the face value of the bills to the financial institutions.
	(o)	Government Grants
		The Company's subsidiaries in China receive government subsidies from local Chinese government agencies in accordance with relevant Chinese government policies. In general, the Company presents the government subsidies received as part of other income unless the subsidies received are earmarked to compensate a specific expense, which have been accounted for by offsetting the specific expense, such as research and development expense or interest expenses. Unearned government subsidies received are deferred for recognition until the criteria for such recognition could be met.
		Grants applicable to land are amortized over the life of the depreciable facilities constructed on it. For research and development expenses, the Company matches and offsets the government grants with the expenses of the research and development activities as specified in the grant approval document in the corresponding period when such expenses are incurred.
		No government grants were offset against the finance costs for the years ended September 30, 2012 and 2013.
	(p)	Share-based Compensation
		The Company adopted the provisions of ASC Topic 718 which requires the Company to measure and recognize compensation expenses for an award of an equity instrument based on the grant-date fair value. The cost is recognized over the vesting period (or the requisite service period). ASC Topic 718 also requires the Company to measure the cost of a liability-classified award based on its current fair value. The fair value of the award will be re-measured subsequently at each reporting date through the settlement date. Changes in fair value during the requisite service period are recognized as compensation cost over that period. Further, ASC Topic 718 requires the Company to estimate forfeitures in calculating the expense related to stock-based compensation.
		The fair value of each option award is estimated on the date of grant using the Black-Scholes Option Valuation Model. The expected volatility was based on the historical volatilities of the Company's listed common stocks in the United States and other relevant market information. The Company uses historical data to estimate share option exercises and employee departure behavior used in the valuation model. The expected terms of share options granted is derived from the output of the option pricing model and represents the period of time that share options granted are expected to be outstanding. Since the share options once exercised will primarily trade in the U.S. capital market, the risk-free rate for periods within the contractual term of the share option is based on the U.S. Treasury yield curve in effect at the time of grant.
	(q)	Retirement and Other Post-retirement Benefits
		Contributions to retirement schemes (which are defined contribution plans) are charged to cost of revenues, research and development expenses, sales and marketing expenses and general and administrative expenses in the statement of operations and comprehensive loss as and when the related employee service is provided.
	(r)	Loss per Share
		Basic loss per share is computed by dividing net loss by the weighted average number of ordinary shares outstanding during the year. Diluted loss per share is computed by dividing net loss by the sum of the weighted average number of ordinary shares outstanding and dilutive potential ordinary shares during the year.
(s)	Use of Estimates
	The preparation of the consolidated financial statements in accordance with US GAAP requires management of the Company to make a number of estimates and assumptions relating to the reported amount of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the period. Actual results could differ from those estimates. Significant items subject to such estimates and assumptions include the recoverability of the carrying amount of long-lived assets; valuation allowance for obsolete inventories, receivables and deferred tax assets; provision for sales returns; valuation of share-based compensation expense; and fair value assessment of financial guarantees. Actual results could differ from those estimates.
(t)	Segment Reporting
	The Company uses the “management approach” in determining reportable operating segments. The management approach considers the internal organization and reporting used by the Company's chief operating decision maker for making operating decisions and assessing performance as the source for determining the Company's reportable segments. Management, including the chief operating decision maker, reviews operating results solely by monthly revenue of Li-ion rechargeable batteries (but not by sub-product type or geographic area) and operating results of the Company and, as such, the Company has determined that the Company has one operating segment as defined by ASC Topic 280 “Segment Reporting”.
(u)	Commitments and Contingencies
	Liabilities for loss contingencies arising from claims, assessments, litigation, fines and penalties and other sources are recorded when it is probable that a liability has been incurred and the amount of the assessment can be reasonably estimated.
(v)	Recently Issued Accounting Standards
	In December 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2011-11 — Balance Sheet (Topic 210). The objective of this update is to provide enhanced disclosures that will enable users of its financial statements to evaluate the effect or potential effect of netting arrangements on an entity's financial position. This includes the effect or potential effect of rights of setoff associated with an entity's recognized assets and recognized liabilities within the scope of this update. The amendments require enhanced disclosures by requiring improved information about financial instruments and derivative instruments that are either (1) offset in accordance with either Section 210-20-45 or Section 815-10-45 or (2) subject to an enforceable master netting arrangement or similar agreement, irrespective of whether they are offset in accordance with either Section 210-20-45 or Section 815-10-45. An entity is required to apply the amendments for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods. An entity should provide the disclosures required by those amendments retrospectively for all comparative periods presented. The Company does not expect the adoption of the provisions in this update will have a significant impact on its consolidated financial statements.
	In February 2013, the FASB issued ASU No. 2013-02 — Comprehensive Income (Topic 220). The objective of this update is to improve the reporting of reclassifications out of accumulated other comprehensive income. The amendments in this update seek to attain that objective by requiring an entity to report the effect of significant reclassifications out of accumulated other comprehensive income on the respective line items in net income if the amount being reclassified is required under U.S. generally accepted accounting principles (GAAP) to be reclassified in its entirety to net income. For other amounts that are not required under U.S. GAAP to be reclassified in their entirety to net income in the same reporting period, an entity is required to cross-reference other disclosures required under U.S. GAAP that provide additional detail about those amounts. This would be the case when a portion of the amount reclassified out of accumulated other comprehensive income is reclassified to a balance sheet account (for example, inventory) instead of directly to income or expense in the same reporting period. For public entities, the amendments are effective prospectively for reporting periods beginning after December 15, 2012. The Company does not expect the adoption of the provisions in this update will have a significant impact on its consolidated financial statements.
	In March 2013, the FASB issued ASU No. 2013-05 — Foreign Currency Matters, (Topic 830): Parent's Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity, to resolve a diversity in accounting for the cumulative translation adjustment of foreign currency upon derecognition of a foreign subsidiary or group of assets. ASU 2013-05 requires the parent to apply the guidance in Subtopic 830-30 to release any related cumulative translation adjustment into net income when a reporting entity (parent) ceases to have a controlling financial interest in a subsidiary or group of assets within a foreign entity. Accordingly, the cumulative translation adjustment should be released into net income only if the sale or transfer results in the complete or substantially complete liquidation of the foreign entity in which the subsidiary or group of assets had resided. Further, ASU 2013-05 clarified that the parent should apply the guidance in subtopic 810-10 if there is a sale of an investment in a foreign entity, including both (1) events that result in the loss of a controlling financial interest in a foreign entity and (2) events that result in an acquirer obtaining control of an acquiree in which it held an equity interest immediately before the acquisition date. Accordingly, the cumulative translation adjustment should be released into net income upon the occurrence of those events. The guidance is effective prospectively for fiscal years (and interim reporting periods within those years) beginning after December 15, 2013. The guidance should be applied prospectively to derecognition events occurring after the effective date. Prior periods should not be adjusted. Early adoption is permitted. If an entity elects to early adopt the guidance, it should apply the guidance as of the beginning of the entity's fiscal year of adoption. The Company does not expect ASU 2013-05 to have a significant impact on its consolidated results of operations and financial condition.
	In July 2013, the FASB issued ASU No. 2013-11, Income Taxes (Topic 740). The amendments in this update provide guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss carry forward, similar tax loss, or tax credit carry forward exists. These amendments provide that an unrecognized tax benefit, or a portion thereof, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carry forward, a similar tax loss, or a tax credit carry forward, except to the extent that a net operating loss carry forward, a similar tax loss, or a tax credit carry forward is not available at the reporting date to settle any additional income taxes that would result from disallowance of a tax position, or the tax law does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose, then the unrecognized tax benefit should be presented as a liability. The amendments in this update are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. Early adoption is permitted. The Company does not expect ASU 2013-11 to have a significant impact on its consolidated results of operations and financial condition.
	Other accounting standards that have been issued or proposed by the FASB or other standards-setting bodies that do not require adoption until a future date are not expected to have a material impact on the Company's consolidated financial statements upon adoption.

After the filing of the 2006 Form 10-K, the Company's previously filed registration statement on Form S-1 was no longer available for resale by the selling shareholders whose shares were included in such Form S-1. Under the registration rights agreement, those selling shareholders became eligible for liquidated damages from the Company relating to the above two events totaling approximately $1,051,000.

The Company may have become liable for liquidated damages to certain shareholders whose shares were included in a resale registration statement on Form S-3 that the Company filed pursuant to a registration rights agreement that the Company entered into with such shareholders in November 2007. Under the registration rights agreement, among other things, if a registration statement filed pursuant thereto was not declared effective by the SEC by the 100th calendar day after the closing of the Company's private placement on November 9, 2007, or the “Effectiveness Deadline”, then the Company would be liable to pay partial liquidated damages to each such investor of (a) 1.5% of the aggregate purchase price paid by such investor for the shares it purchased on the one month anniversary of the Effectiveness Deadline; (b) an additional 1.5% of the aggregate purchase price paid by such investor every thirtieth day thereafter (pro rated for periods totaling less than thirty days) until the earliest of the effectiveness of the registration statement, the ten-month anniversary of the Effectiveness Deadline and the time that the Company is no longer required to keep such resale registration statement effective because either such shareholders have sold all of their shares or such shareholders may sell their shares pursuant to Rule 144 without volume limitations; and (c) 0.5% of the aggregate purchase price paid by such investor for the shares it purchased in our November 2007 private placement on each of the following dates: the ten-month anniversary of the Effectiveness Deadline and every thirtieth day thereafter (pro rated for periods totaling less than thirty days), until the earlier of the effectiveness of the registration statement and the time that the Company no longer is required to keep such resale registration statement effective because either such shareholders have sold all of their shares or such shareholders may sell their shares pursuant to Rule 144 without volume limitations. Such liquidated damages would bear interest at the rate of 1% per month (prorated for partial months) until paid in full.
			On December 21, 2007, pursuant to the registration rights agreement, the Company filed a registration statement on Form S-3, which was declared effective by the SEC on May 7, 2008.

Fair Value of Financial Instruments [Text Block]	'
	19	Fair Value of Financial Instruments
		ASC Topic 820, Fair Value Measurement and Disclosures , defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. This topic also establishes a fair value hierarchy, which requires classification based on observable and unobservable inputs when measuring fair value. Certain current assets and current liabilities are financial instruments. Management believes their carrying amounts are a reasonable estimate of fair value because of the short period of time between the origination of such instruments and their expected realization and, if applicable, their current interest rates are equivalent to interest rates currently available. The three levels of valuation hierarchy are defined as follows:
		-	Level 1 inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets.
		-	Level 2 inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the assets or liability, either directly or indirectly, for substantially the full term of the financial instruments.
		-	Level 3 inputs to the valuation methodology are unobservable and significant to the fair value measurement.
	The carrying amounts of financial assets and liabilities, such as cash and cash equivalents, pledged deposits, trade accounts receivable, other receivables, short-term bank loans, long-term bank loans, other long-term and short-term loans, other long-term payable, accounts and bills payable and other payables approximate their fair values because of the short maturity of these instruments or the rate of interest of these instruments approximate the market rate of interest.

Ltd owns assets including land use rights covering an area of approximately 1,330,000 square meters and buildings thereon in Hubei, the PRC, and should be financially capable to repay the above mentioned loans upon maturity in April 2014.
		It is a common practice among companies in the region of China where the Company is located to provide guarantees for bank debts of existing or prospective business partners with no consideration given. It is considered a “favor for favor” business practice and is commonly required by the lending banks in these cases.
		The Company has also guaranteed the loans of a related party under the common control of Mr. Xiangqian Li in the amount of approximately $11.2 million and $4.9 million as of September 30, 2012 and 2013, respectively.

As of September 30, 2013, the Company has paid China Agricultural Bank an amount of RMB46,490,253 ($7.5 million). The Company was able to recover an indemnification amount from Shenzhen Langjin that totaled RMB46,456,681 ($7.5 million).

		Under PRC regulations, Shenzhen BAK, BAK Electronics and BAK Tianjin and BAK Dalian (“the PRC subsidiaries”) may pay dividends only out of their accumulated profits, if any, determined in accordance with PRC GAAP. In addition, the PRC subsidiaries are required to set aside at least 10% of their after-tax net profits each year, if any, to fund the statutory general reserve until the balance of the reserves reaches 50% of their registered capital. The statutory general reserves are not distributable in the form of cash dividends to the Company and can be used to make up cumulative prior year losses, if any, and may be converted into share capital by the issue of new shares to shareholders in proportion to their existing shareholdings, or by increasing the par value of the shares currently held by them, provided that the reserve balance after such issue is not less than 25% of the registered capital. As of September 30, 2012 and 2013 additional transfers of $86,789,695 and $86,958,843 were required before the statutory general reserve reached 50% of the registered capital of the PRC subsidiaries. As of September 30, 2012 and 2013, $7,786,157 had been appropriated from retained earnings and set aside for statutory general reserves by the PRC subsidiaries. BAK Tianjin did not have after-tax net profits since its incorporation and therefore no appropriation was made to fund its statutory general reserve as of September 30, 2012 and 2013.
		As of September 30, 2012 and 2013, the amount of restricted net assets of the PRC subsidiaries, which may not be transferred to the Company in the forms of loans, advances or cash dividends by the subsidiaries without the consent of a third party, was approximately 5% and nil of the Company's consolidated net assets as discussed above.

Summary_of_Significant_Account1

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Sep. 30, 2013
Principles of Consolidation [Policy Text Block]	'
	(a)	Principles of Consolidation

Cash and Cash Equivalents [Policy Text Block]	'
	(b)	Cash and Cash Equivalents
		Cash consists of cash on hand and in banks excluding pledged deposits. The Company considers all highly liquid debt instruments, with initial terms of less than three months to be cash equivalents. As of September 30, 2012 and 2013, there were no cash equivalents.
Trade Accounts Receivable [Policy Text Block]	'
	(c)	Trade Accounts Receivable
		Trade accounts receivable are recorded at the invoiced amount, net of allowances for doubtful accounts and sales returns. The allowance for doubtful accounts is the Company's best estimate of the amount of probable credit losses in the Company's existing trade accounts receivable. The Company determines the allowance based on historical write-off experience, customer specific facts and economic conditions. Bad debt expense is included in general and administrative expenses.
		Outstanding accounts receivable balances are reviewed individually for collectability. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote.
Inventories [Policy Text Block]	'
	(d)	Inventories
		Inventories are stated at the lower of cost or market. The cost of inventories is determined using the weighted average cost method, and includes expenditures incurred in acquiring the inventories and bringing them to their existing location and condition. In case of finished goods and work in progress, the cost includes an appropriate share of production overhead based on normal operating capacity.
		The Company regularly reviews the cost of inventories against their estimated fair market value and records a lower of cost or market write-down for inventories that have costs in their excess of estimated market value.
Property, Plant and Equipment [Policy Text Block]	'
	(e)	Property, Plant and Equipment
		Property, plant and equipment (except construction in progress) are stated at cost less accumulated depreciation and impairment charges. Depreciation is calculated based on the straight-line method (after taking into account their respective estimated residual values) over the estimated useful lives of the assets as follows:
	Buildings	30 - 40 years
	Machinery and equipment	5 - 12 years
	Office equipment	5 years
	Motor vehicles	5 - 8 years
	The cost and accumulated depreciation of property, plant and equipment sold are removed from the consolidated balance sheets and resulting gains or losses are recognized in the consolidated statements of operations and comprehensive loss.
	Construction in progress mainly represents expenditures in respect of the Company's corporate campus, including offices, factories and staff dormitories, under construction. All direct costs relating to the acquisition or construction of the Company's corporate campus and equipment, including interest charges on borrowings, are capitalized as construction in progress. No depreciation is provided in respect of construction in progress.
	A long-lived asset to be disposed of by abandonment continues to be classified as held and used until it is disposed of.
Prepaid Land Use Rights [Policy Text Block]	'
	(f)	Prepaid Land Use Rights
		Land use rights are carried at cost and amortized on a straight-line basis over the period of rights of 50 years.
Foreign Currency Transactions and Translations PForeign Currency Transactions and Translationolicy [Policy Text Block]	'
	(g)	Foreign Currency Transactions and Translation
		The reporting currency of the Company is the United States dollar (“US dollar”). The financial records of the Company's PRC operating subsidiaries are maintained in their local currency, the Renminbi (“RMB”), which is the functional currency. The financial records of the Company's subsidiaries established in other countries are maintained in their local currencies. Assets and liabilities of the subsidiaries are translated into the reporting currency at the exchange rates at the balance sheet date, equity accounts are translated at historical exchange rates, and income and expenses items are translated using the average rate for the period. The translation adjustments are recorded in accumulated other comprehensive income under shareholders' equity.
		Monetary assets and liabilities denominated in currencies other than the applicable functional currencies are translated into the functional currencies at the prevailing rates of exchange at the balance sheet date. Nonmonetary assets and liabilities are re-measured into the applicable functional currencies at historical exchange rates. Transactions in currencies other than the applicable functional currencies during the period are converted into the functional currencies at the applicable rates of exchange prevailing at the transaction dates. Transaction gains and losses are recognized in the consolidated statements of operations and comprehensive loss.
		RMB is not a fully convertible currency. All foreign exchange transactions involving RMB must take place either through the People's Bank of China (the “PBOC”) or other institutions authorized to buy and sell foreign exchange. The exchange rates adopted for the foreign exchange transactions are the rates of exchange quoted by the PBOC, which are determined largely by supply and demand. Translation of amounts from RMB into US dollars has been made at the following exchange rates for the respective years:
		30-Sep-13
		Balance sheet, except for equity accounts	RMB6.1211 to US$1.00
		Income statement and cash flows	RMB6.1894 to US$1.00
		30-Sep-12
		Balance sheet	RMB6.2857 to US$1.00

Intangible Assets [Policy Text Block]	'
	(h)	Intangible Assets
		Intangible assets are stated in the balance sheet at cost less accumulated amortization and impairment, if any.

		Trademarks	10 years
		Technology	7 - 10 years
		Computer software	3 - 10 years
Impairment of Long-lived Assets [Policy Text Block]	'
	(i)	Impairment of Long-lived Assets
		Long-lived assets, which include property, plant and equipment, prepaid land use rights and intangible assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable.
		Recoverability of long-lived assets to be held and used is measured by a comparison of the carrying amount of an asset to the estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated undiscounted future cash flows, an impairment charge is recognized by the amount by which the carrying amount of the asset exceeds the fair value of the asset.
Revenue Recognition [Policy Text Block]	'
	(j)	Revenue Recognition
		The Company recognizes revenue on product sales when products are delivered and the customer takes ownership and assumes risk of loss, collection of the relevant receivable is probable, persuasive evidence of an arrangement exists and the sales price is fixed or determinable.
		Net sales of products represent the invoiced value of goods sold, net of value added taxes (“VAT”), sales returns, trade discounts and allowances. The Company is subject to VAT which is levied on the majority of the products of Shenzhen BAK, BAK Electronics and BAK Tianjin at the rate of 17% on the invoiced value of sales. Output VAT is borne by customers in addition to the invoiced value of sales and input VAT is borne by the Company in addition to the invoiced value of purchases to the extent not refunded for export sales. Provision for sales returns are recorded as a reduction of revenue in the same period that revenue is recognized. The provision for sales returns, which is based on historical sales returns data, is the Company's best estimate of the amount of goods that will be returned from its customers.
Cost of Revenues [Policy Text Block]	'
	(k)	Cost of Revenues
		Cost of revenues consists primarily of material costs, employee compensation, depreciation and related expenses, which are directly attributable to the production of products. Write-down of inventories to lower of cost or market is also recorded in cost of revenues.
Income Taxes [Policy Text Block]	'
	(l)	Income Taxes
		Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carry-forwards. Deferred tax assets are reduced by a valuation allowance to the extent management concludes it is more likely than not that the assets will not be realized. Deferred tax assets and liabilities are measured using enacted tax rates applied to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the statement of operations and comprehensive loss in the period that includes the enactment date.
		The impact of an uncertain income tax positions on the income tax return must be recognized at the largest amount that is more-likely-than not to be sustained upon audit by the relevant tax authority. An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained. Interest and penalties on income taxes will be classified as a component of the provisions for income taxes.
Research and Development and Advertising Expenses [Policy Text Block]	'
	(m)	Research and Development and Advertising Expenses
		Research and development and advertising expenses are expensed as incurred. Research and development expenses consist primarily of remuneration for research and development staff, depreciation and maintenance expenses of research and development equipment and material costs for research and development. Advertising expenses, including in sales and marketing expenses, amounted to $236,145 and $1,392 for the years ended September 30, 2012 and 2013, respectively.
Bills Payable [Policy Text Block]	'
	(n)	Bills Payable
		Bills payable represent bills issued by financial institutions to the Company's vendors. The Company's vendors receive payments from the financial institutions directly upon maturity of the bills and the Company is obliged to repay the face value of the bills to the financial institutions.
Government Grants [Policy Text Block]	'
	(o)	Government Grants
		The Company's subsidiaries in China receive government subsidies from local Chinese government agencies in accordance with relevant Chinese government policies. In general, the Company presents the government subsidies received as part of other income unless the subsidies received are earmarked to compensate a specific expense, which have been accounted for by offsetting the specific expense, such as research and development expense or interest expenses. Unearned government subsidies received are deferred for recognition until the criteria for such recognition could be met.
		Grants applicable to land are amortized over the life of the depreciable facilities constructed on it. For research and development expenses, the Company matches and offsets the government grants with the expenses of the research and development activities as specified in the grant approval document in the corresponding period when such expenses are incurred.
		No government grants were offset against the finance costs for the years ended September 30, 2012 and 2013.
Share-based Compensation [Policy Text Block]	'
	(p)	Share-based Compensation
		The Company adopted the provisions of ASC Topic 718 which requires the Company to measure and recognize compensation expenses for an award of an equity instrument based on the grant-date fair value. The cost is recognized over the vesting period (or the requisite service period). ASC Topic 718 also requires the Company to measure the cost of a liability-classified award based on its current fair value. The fair value of the award will be re-measured subsequently at each reporting date through the settlement date. Changes in fair value during the requisite service period are recognized as compensation cost over that period. Further, ASC Topic 718 requires the Company to estimate forfeitures in calculating the expense related to stock-based compensation.
		The fair value of each option award is estimated on the date of grant using the Black-Scholes Option Valuation Model. The expected volatility was based on the historical volatilities of the Company's listed common stocks in the United States and other relevant market information. The Company uses historical data to estimate share option exercises and employee departure behavior used in the valuation model. The expected terms of share options granted is derived from the output of the option pricing model and represents the period of time that share options granted are expected to be outstanding. Since the share options once exercised will primarily trade in the U.S. capital market, the risk-free rate for periods within the contractual term of the share option is based on the U.S. Treasury yield curve in effect at the time of grant.
Retirement and Other Post-retirement Benefits [Policy Text Block]	'
	(q)	Retirement and Other Post-retirement Benefits
		Contributions to retirement schemes (which are defined contribution plans) are charged to cost of revenues, research and development expenses, sales and marketing expenses and general and administrative expenses in the statement of operations and comprehensive loss as and when the related employee service is provided.
Loss per share [Policy Text Block]	'
	(r)	Loss per Share
		Basic loss per share is computed by dividing net loss by the weighted average number of ordinary shares outstanding during the year. Diluted loss per share is computed by dividing net loss by the sum of the weighted average number of ordinary shares outstanding and dilutive potential ordinary shares during the year.
Use of Estimates [Policy Text Block]	'
	(s)	Use of Estimates
		The preparation of the consolidated financial statements in accordance with US GAAP requires management of the Company to make a number of estimates and assumptions relating to the reported amount of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the period. Actual results could differ from those estimates. Significant items subject to such estimates and assumptions include the recoverability of the carrying amount of long-lived assets; valuation allowance for obsolete inventories, receivables and deferred tax assets; provision for sales returns; valuation of share-based compensation expense; and fair value assessment of financial guarantees. Actual results could differ from those estimates.
Segment Reporting [Policy Text Block]	'
	(t)	Segment Reporting
		The Company uses the “management approach” in determining reportable operating segments. The management approach considers the internal organization and reporting used by the Company's chief operating decision maker for making operating decisions and assessing performance as the source for determining the Company's reportable segments. Management, including the chief operating decision maker, reviews operating results solely by monthly revenue of Li-ion rechargeable batteries (but not by sub-product type or geographic area) and operating results of the Company and, as such, the Company has determined that the Company has one operating segment as defined by ASC Topic 280 “Segment Reporting”.
Commitments and Contingencies [Policy Text Block]	'
	(u)	Commitments and Contingencies
		Liabilities for loss contingencies arising from claims, assessments, litigation, fines and penalties and other sources are recorded when it is probable that a liability has been incurred and the amount of the assessment can be reasonably estimated.
Recently Issued Accounting Standards [Policy Text Block]	'
	(v)	Recently Issued Accounting Standards
		In December 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2011-11 — Balance Sheet (Topic 210). The objective of this update is to provide enhanced disclosures that will enable users of its financial statements to evaluate the effect or potential effect of netting arrangements on an entity's financial position. This includes the effect or potential effect of rights of setoff associated with an entity's recognized assets and recognized liabilities within the scope of this update. The amendments require enhanced disclosures by requiring improved information about financial instruments and derivative instruments that are either (1) offset in accordance with either Section 210-20-45 or Section 815-10-45 or (2) subject to an enforceable master netting arrangement or similar agreement, irrespective of whether they are offset in accordance with either Section 210-20-45 or Section 815-10-45. An entity is required to apply the amendments for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods. An entity should provide the disclosures required by those amendments retrospectively for all comparative periods presented. The Company does not expect the adoption of the provisions in this update will have a significant impact on its consolidated financial statements.
		In February 2013, the FASB issued ASU No. 2013-02 — Comprehensive Income (Topic 220). The objective of this update is to improve the reporting of reclassifications out of accumulated other comprehensive income. The amendments in this update seek to attain that objective by requiring an entity to report the effect of significant reclassifications out of accumulated other comprehensive income on the respective line items in net income if the amount being reclassified is required under U.S. generally accepted accounting principles (GAAP) to be reclassified in its entirety to net income. For other amounts that are not required under U.S. GAAP to be reclassified in their entirety to net income in the same reporting period, an entity is required to cross-reference other disclosures required under U.S. GAAP that provide additional detail about those amounts. This would be the case when a portion of the amount reclassified out of accumulated other comprehensive income is reclassified to a balance sheet account (for example, inventory) instead of directly to income or expense in the same reporting period. For public entities, the amendments are effective prospectively for reporting periods beginning after December 15, 2012. The Company does not expect the adoption of the provisions in this update will have a significant impact on its consolidated financial statements.
