Organization, Consolidation and Presentation of Financial Statements [Abstract]
Principal Activities, Basis of Presentation and Organization	1. Principal Activities, Basis of Presentation and Organization Principal Activities CBAK Energy Technology, Inc. (formerly known as China BAK Battery, Inc.) ("CBAK" or the "Company") 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. CBAK 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") high power rechargeable batteries. Prior to the disposal of BAK International Limited ("BAK International") and its subsidiaries (see below), the batteries produced by the Company were 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 vehicles, and general industrial applications. After the disposal of BAK International and its subsidiaries on June 30, 2014, the Company will focus on the manufacture, commercialization and distribution of high power lithium ion rechargeable batteries for use in cordless power tools, light electric vehicles, hybrid electric vehicles, electric cars, electric busses, uninterruptable power supplies and other high power 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". On January 10, 2017, the Company filed Articles of Merger with the Secretary of State of Nevada to effectuate a merger between the Company and the Company's newly formed, wholly owned subsidiary, CBAK Merger Sub, Inc. (the "Merger Sub"). According to the Articles of Merger, effective January 16, 2017, the Merger Sub merged with and into the Company with the Company being the surviving entity (the "Merger"). As permitted by Chapter 92A.180 of Nevada Revised Statutes, the sole purpose of the Merger was to effect a change of the Company's name. Effective November 30, 2018, the trading symbol for common stock of the Company was changed from CBAK to CBAT. Effective at the opening of business on June 21, 2019, the Company's common stock started trading on the Nasdaq Capital Market. Basis of Presentation and Organization On November 6, 2004, BAK International, a non-operating holding company that had substantially the same shareholders as Shenzhen BAK Battery Co., Ltd ("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. 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 CBAK, BAK International and the shareholders of BAK International on January 20, 2005. 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. 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 ("Mr. Li"), 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. 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. 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. Li, Mr. 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. 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. Li regarding the shares, and Mr. 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. 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 June 30, 2015amounted 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 December 31, 2020, the Company had not received any 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 the Company also have transferred 73,749 shares relating to the 2005 performance threshold to the investors who had entered the "2008 Settlement Agreements" with us in fiscal year 2008, pursuant to "Li Settlement Agreement" and "2008 Settlement Agreements", neither Mr. Li nor the Company had any remaining obligations to those related investors who participated in the Company's January 2005 private placement relating to the escrow shares.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies and Practices	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 up to the date of disposal. All significant intercompany 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. (c) Trade Accounts and Bills Receivable Trade accounts and bills 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. 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 net realizable value. 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. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The Company records adjustments to its inventory for estimated obsolescence or diminution in net realizable value equal to the difference between the cost of the inventory and the estimated net realizable value. At the point of loss recognition, a new cost basis for that inventory is established, and subsequent changes in facts and circumstances do not result in the restoration or increase in that newly established cost basis. (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 5 – 35 years Machinery and equipment 1 – 15 years Office equipment 1 – 5 years Motor vehicles 5 – 10 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) Lease (i) Right of use assets Prior to the adoption of Accounting Standards Update ("ASU") No. 2016-02, Leases (Topic 842) ("ASC 842"), land use rights are carried at cost and amortized on a straight-line basis over the period of rights of 50 years. Upon the adoption of ASC 842 on January 1, 2019, land use rights acquired are assessed in accordance with ASC 842 and recognized in right-of-use assets if they meet the definition of lease. (ii) Net Investment in Sales Type Leases The Company derives a portion of its revenue from vehicles leasing arrangements. Such arrangements provide for monthly payments covering the vehicles sales and interest. These arrangements meet the criteria to be accounted for as sales-type leases. A lease is classified as a sales-type lease if at least one of the following criteria is met: (1) the lease transfers ownership of the underlying asset to the lessee, (2) the lease grants the lessee an option to purchase the underlying asset that the lessee is reasonably certain to exercise, (3) the lease term is for a major part of the remaining economic life of the underlying asset, (4) the present value of the sum of the lease payments equals or exceeds substantially all of the fair value of the underlying assets, or (5) the underlying asset is of such a specialized nature that it is expected to have no alternative use to the lessor at the end of the lease term. Accordingly, vehicle sale net of cost is recorded as other income and recognized upon delivery of the vehicle and its acceptance by the customer. Upon the recognition of such revenue, an asset is established for the investment in sales-type leases. Interests are recognized monthly over the lease term. (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 expense items are translated using the average rate for the period. The translation adjustments are recorded in accumulated other comprehensive loss 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 remeasured 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. 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 periods: Year ended December 31, 2019 Balance sheet, except for equity accounts RMB 6.9630 to US$1.00 Income statement and cash flows RMB 6.9073 to US$1.00 Year ended December 31, 2020 Balance sheet, except for equity accounts RMB 6.5286 to US$1.00 Income statement and cash flows RMB 6.9032 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: Computer software 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. Fair value is generally measured based on either quoted market prices, if available, or discounted cash flow analyses. (j) Revenue Recognition The Company recognizes revenues when its customer obtains control of promised goods or services, in an amount that reflects the consideration which it expects to receive in exchange for those goods. The Company recognizes revenues following the five step model prescribed under ASU No. 2014-09: (i) identify contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenues when (or as) we satisfy the performance obligation. Revenues from product sales are recognized when the customer obtains control of the Company's product, which occurs at a point in time, typically upon delivery to the customer. The Company expenses incremental costs of obtaining a contract as and when incurred if the expected amortization period of the asset that it would have recognized is one year or less or the amount is immaterial. Revenues from product sales are recorded net of reserves established for applicable discounts and allowances that are offered within contracts with the Company's customers. Product revenue reserves, which are classified as a reduction in product revenues, are generally characterized in the categories: discounts and returns. These reserves are based on estimates of the amounts earned or to be claimed on the related sales and are classified as reductions of accounts receivable as the amount is payable to the Company's customer. (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. The significant uncertain tax position arose from the subsidies granted by the local government for the Company's PRC subsidiary, which may be modified or challenged by the central government or the tax authority. A reconciliation of January 1, 2019, through December 31, 2020 amount of unrecognized tax benefits excluding interest and penalties ("Gross UTB") is as follows: Gross UTB Surcharge Net UTB Balance as of January 1, 2019 $ 7,129,285 - 7,129,285 Decrease in unrecognized tax benefits taken in current period (86,703 ) - (86,703 ) Balance as of December 31, 2019 7,042,582 - 7,042,582 Increase in unrecognized tax benefits taken in current year 468,600 - 468,600 Balance as of December 31, 2020 $ 7,511,182 $ - $ 7,511,182 As of December 31, 2019 and 2020, the Company had not accrued any interest and penalties related to unrecognized tax benefits. (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 material costs for research and development. (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) Warranties The Company provides a manufacturer's warranty on all its products. It accrues a warranty reserve for the products sold, which includes management's best estimate of the projected costs to repair or replace items under warranty. These estimates are based on actual claims incurred to date and an estimate of the nature, frequency and costs of future claims. These estimates are inherently uncertain given the Company's relatively short history of sales of its current products, and changes to its historical or projected warranty experience may cause material changes to the warranty reserve in the future. (p) 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, interest expenses and removal costs. 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. (q) 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 remeasured 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. (r) Retirement and Other Postretirement 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. (s) Loss per Share Basic and diluted loss per share is computed by dividing net loss by the weighted average number of ordinary shares outstanding during the year. (t) 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 revenue recognition, the recoverability of the carrying amount of long-lived assets, unrecognized tax benefits, impairment on inventories, valuation allowance for receivables and deferred tax assets, provision for warranty and sales returns, valuation of share-based compensation expense and warrants liability. Actual results could differ from those estimates. (u) 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". (v) 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. (w) Warrant Liability For warrants that are not indexed to the Company's stock, the Company records the fair value of the issued warrants as a liability at each balance sheet date and records changes in the estimated fair value as a non-cash gain or loss in the consolidated statement of operations and comprehensive income. The warrant liability is recognized in the balance sheet at the fair value (level 3). The fair value of these warrants has been determined using the Binomial model. Recently Adopted Accounting Standards In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement, which modifies the disclosure requirements for Level 1, Level 2 and Level 3 instruments in the fair value hierarchy. The guidance is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years, with early adoption permitted for any eliminated or modified disclosures. The Company applied the new standard beginning January 1, 2020. Recently Issued Accounting Standards In May 2019, the Financial Accounting Standards Board ("FASB") issued ASU 2019-05, which is an update to ASU Update No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which introduced the expected credit losses methodology for the measurement of credit losses on financial assets measured at amortized cost basis, replacing the previous incurred loss methodology. The amendments in Update 2016-13 added Topic 326, Financial Instruments—Credit Losses, and made several consequential amendments to the Codification. Update 2016-13 also modified the accounting for available-for-sale debt securities, which must be individually assessed for credit losses when fair value is less than the amortized cost basis, in accordance with Subtopic 326-30, Financial Instruments— Credit Losses—Available-for-Sale Debt Securities. The amendments in this ASU address those stakeholders' concerns by providing an option to irrevocably elect the fair value option for certain financial assets previously measured at amortized cost basis. For those entities, the targeted transition relief will increase comparability of financial statement information by providing an option to align measurement methodologies for similar financial assets. Furthermore, the targeted transition relief also may reduce the costs for some entities to comply with the amendments in Update 2016-13 while still providing financial statement users with decision-useful information. ASU 2019-05 is effective for the Company for fiscal year beginning after December 15, 2022. The Company is currently evaluating the impact of this new standard on its condensed consolidated financial statements and related disclosures. In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes, which simplifies the accounting for income taxes, eliminates certain exceptions within ASC 740, Income Taxes, and clarifies certain aspects of the current guidance to promote consistent application among reporting entities. The guidance is effective for fiscal years beginning after December 15, 2020, and interim periods within those fiscal years, with early adoption permitted. Upon adoption, the Company must apply certain aspects of this standard retrospectively for all periods presented while other aspects are applied on a modified retrospective basis through a cumulative-effect adjustment to retained earnings as of the beginning of the fiscal year of adoption. The Company is evaluating the impact this update will have on its financial statements. In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848) (Topic 718): Improvemen20-04 contains practical expedients for reference rate reform related activities that impact debt, leases, derivatives and other contracts. The guidance in ASU 2020-04 is optional and may be elected over time as reference rate reform activities occur. The Company continues to evaluate the impact of the guidance and may apply the elections as applicable as changes in the market occur. In August 2020, the FASB issued ASU 2020-06, Debt - Debt with Conversion and Other Options (Subtopic 470- 20) and Derivatives and Hedging - Contracts in Entity's Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity's Own Equity ("ASU 2020-06"), which simplifies the accounting for certain financial instruments with characteristics of liabilities and equity. This ASU (1) simplifies the accounting for convertible debt instruments and convertible preferred stock by removing the existing guidance in ASC 470-20, Debt: Debt with Conversion and Other Options, that requires entities to account for beneficial conversion features and cash conversion features in equity, separately from the host convertible debt or preferred stock; (2) revises the scope exception from derivative accounting in ASC 815-40 for freestanding financial instruments and embedded features that are both indexed to the issuer's own stock and classified in stockholders' equity, by removing certain criteria required for equity classification; and (3) revises the guidance in ASC 260, Earnings Per Share, to require entities to calculate diluted earnings per share (EPS) for convertible instruments by using the if-converted method. In addition, entities must presume share settlement for purposes of calculating diluted EPS when an instrument may be settled in cash or shares. For SEC filers, excluding smaller reporting companies, ASU 2020-06 is effective for fiscal years beginning after December 15, 2021 including interim periods within those fiscal years. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020. For all other entities, ASU 2020-06 is effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. Entities should adopt the guidance as of the beginning of the fiscal year of adoption and cannot adopt the guidance in an interim reporting period. The Company is currently evaluating the impact that ASU 2020-06 may have on its condensed consolidated financial statements and related disclosures. 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.

Income Tax Disclosure [Abstract]
Income Taxes, Deferred Tax Assets and Deferred Tax Liabilities	18. Income Taxes, Deferred Tax Assets and Deferred Tax Liabilities (a) Income taxes in the consolidated statements of comprehensive loss(income) The Company's provision for income taxes expenses (credit) consisted of: December 31, December 31, 2019 2020 PRC income tax $ - $ - Current - - Deferred $ - $ - United States Tax CBAK is a Nevada corporation that is subject to U.S. corporate income tax on its taxable income at a rate of up to 21% for taxable years beginning after December 31, 2017 and U.S. corporate income tax on its taxable income of up to 35% for prior tax years. The U.S. Tax Reform signed into law on December 22, 2017 significantly modified the U.S. Internal Revenue Code by, among other things, reducing the statutory U.S. federal corporate income tax rate from 35% to 21% for taxable years beginning after December 31, 2017; limiting and/or eliminating many business deductions; migrating the U.S. to a territorial tax system with a one-time transition tax on a mandatory deemed repatriation of previously deferred foreign earnings of certain foreign subsidiaries; subject to certain limitations, generally eliminating U.S. corporate income tax on dividends from foreign subsidiaries; and providing for new taxes on certain foreign earnings. Taxpayers may elect to pay the one-time transition tax over eight years, or in a single lump sum. The U.S. Tax Reform also includes provisions for a new tax on GILTI effective for tax years of foreign corporations beginning after December 31, 2017. The GILTI provisions impose a tax on foreign income in excess of a deemed return on tangible assets of controlled foreign corporations ("CFCs"), subject to the possible use of foreign tax credits and a deduction equal to 50 percent to offset the income tax liability, subject to some limitations. To the extent that portions of CBAK's U.S. taxable income, such as Subpart F income or GILTI, are determined to be from sources outside of the U.S., subject to certain limitations, the Company may be able to claim foreign tax credits to offset its U.S. income tax liabilities. If dividends that CBAK receives from its subsidiaries are determined to be from sources outside of the U.S., subject to certain limitations, CBAK will generally not be required to pay U.S. corporate income tax on those dividends. Any liabilities for U.S. corporate income tax will be accrued in the Company's consolidated statements of comprehensive loss and estimated tax payments will be made when required by U.S. law. No provision for income taxes in the United States has been made as CBAK had no taxable income for the years ended December 31, 2019 and 2020. Hong Kong Tax BAK Asia is subject to Hong Kong profits tax rate of 16.5% and did not have any assessable profits arising in or derived from Hong Kong for the years ended December 31, 2019 and 2020 and accordingly no provision for Hong Kong profits tax was made in these periods. PRC Tax The CIT Law in China applies an income tax rate of 25% to all enterprises but grants preferential tax treatment to High-New Technology Enterprises. CBAK Power was regarded as a "High-new technology enterprise" pursuant to a certificate jointly issued by the relevant Dalian Government authorities. The certificate was valid for three years commencing from year 2019. Under the preferential tax treatment, CBAK Power was entitled to enjoy a tax rate of 15% for the years from 2019 to 2021 provided that the qualifying conditions as a High-new technology enterprise were met. A reconciliation of the provision for income taxes determined at the statutory income tax rate to the Company's income taxes is as follows: Year ended Year ended Loss before income taxes $ (10,853,435 ) $ (7,846,768 ) United States federal corporate income tax rate 21 % 21 % Income tax credit computed at United States statutory corporate income tax rate (2,279,221 ) (1,647,821 ) Reconciling items: Over provision of deferred taxation in prior year Rate differential for PRC earnings (372,518 ) (318,383 ) Non-taxable income - (435,120 ) Non-deductible expenses 161,576 241,843 Share based payments 161,724 168,826 (Under) Over provision of tax losses (92,668 ) 174,558 Valuation allowance on deferred tax assets 2,421,107 1,816,097 Income tax expenses $ - $ - (b) Deferred tax assets and deferred tax liabilities The tax effects of temporary differences that give rise to significant portions of the deferred tax assets and liabilities as of December 31, 2019 and 2020 are presented below: December 31, December 31, Deferred tax assets Trade accounts receivable $ 1,225,916 $ 1,354,762 Inventories 1,026,483 575,575 Property, plant and equipment 768,975 1,271,986 Provision for product warranty 561,733 497,901 Net operating loss carried forward 29,361,274 31,060,254 Valuation allowance (32,944,381 ) (34,760,478 ) Deferred tax assets, non-current $ - $ - Deferred tax liabilities, non-current $ - $ - As of December 31, 2020, the Company's U.S. entity had net operating loss carry forwards of $103,580,741, of which $102,293 available to reduce future taxable income which will expire in various years through 2035 and $103,478,448 available to offset capital gains recognized in the succeeding 5 tax years. As of December 31, 2020, the Company's PRC subsidiaries had net operating loss carry forwards of $37,536,687, which will expire in various years through 2021 to 2030. Management believes it is more likely than not that the Company will not realize these potential tax benefits as these operations will not generate any operating profits in the foreseeable future. As a result, a valuation allowance was provided against the full amount of the potential tax benefits. According to the PRC Tax Administration and Collection Law, the statute of limitations is three years if the underpayment of taxes is due to computational errors made by the taxpayer or its withholding agent. The statute of limitations extends to five years under special circumstances, which are not clearly defined. In the case of a related party transaction, the statute of limitations is ten years. There is no statute of limitations in the case of tax evasion.

The carrying amounts of financial assets and liabilities, such as cash and cash equivalents, trade accounts and bills receivable, other receivables, balances with former subsidiaries, notes payable, other short-term loans, short-term and long-term bank loans 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. The fair value of warrants was determined using the Binomial Model, with level 3 inputs (Note 21).

Condensed Financial Information Disclosure [Abstract]
CBAK Energy Technology, Inc. (Parent Company)	26. CBAK Energy Technology, Inc. (Parent Company) Under PRC regulations, subsidiaries in PRC ("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 December 31, 2019 and 2020, additional transfers of $56,269,489 and $164,388,965 were required before the statutory general reserve reached 50% of the registered capital of the PRC subsidiaries. As of December 31, 2019 and 2020, there was $1,230,511 appropriation from retained earnings and set aside for statutory general reserves by the PRC subsidiaries. The PRC subsidiaries did not have after tax net profits since its incorporation and therefore no appropriation was made to fund its statutory general reserve as of December 31, 2019 and 2020.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies and Practices (Policies)	12 Months Ended
	Dec. 31, 2020
Accounting Policies [Abstract]
Principles of Consolidation	(a) Principles of Consolidation The consolidated financial statements include the financial statements of the Company and its subsidiaries up to the date of disposal. All significant intercompany balances and transactions have been eliminated prior to consolidation.
Cash and Cash Equivalents	(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.
Trade Accounts and Bills Receivable	(c) Trade Accounts and Bills Receivable Trade accounts and bills 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. 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	(d) Inventories Inventories are stated at the lower of cost or net realizable value. 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. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The Company records adjustments to its inventory for estimated obsolescence or diminution in net realizable value equal to the difference between the cost of the inventory and the estimated net realizable value. At the point of loss recognition, a new cost basis for that inventory is established, and subsequent changes in facts and circumstances do not result in the restoration or increase in that newly established cost basis.
Property, Plant and Equipment	(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 5 – 35 years Machinery and equipment 1 – 15 years Office equipment 1 – 5 years Motor vehicles 5 – 10 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.
Lease	(f) Lease (i) Right of use assets Prior to the adoption of Accounting Standards Update ("ASU") No. 2016-02, Leases (Topic 842) ("ASC 842"), land use rights are carried at cost and amortized on a straight-line basis over the period of rights of 50 years. Upon the adoption of ASC 842 on January 1, 2019, land use rights acquired are assessed in accordance with ASC 842 and recognized in right-of-use assets if they meet the definition of lease. (ii) Net Investment in Sales Type Leases The Company derives a portion of its revenue from vehicles leasing arrangements. Such arrangements provide for monthly payments covering the vehicles sales and interest. These arrangements meet the criteria to be accounted for as sales-type leases. A lease is classified as a sales-type lease if at least one of the following criteria is met: (1) the lease transfers ownership of the underlying asset to the lessee, (2) the lease grants the lessee an option to purchase the underlying asset that the lessee is reasonably certain to exercise, (3) the lease term is for a major part of the remaining economic life of the underlying asset, (4) the present value of the sum of the lease payments equals or exceeds substantially all of the fair value of the underlying assets, or (5) the underlying asset is of such a specialized nature that it is expected to have no alternative use to the lessor at the end of the lease term. Accordingly, vehicle sale net of cost is recorded as other income and recognized upon delivery of the vehicle and its acceptance by the customer. Upon the recognition of such revenue, an asset is established for the investment in sales-type leases. Interests are recognized monthly over the lease term.
Foreign Currency Transactions and Translation	(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 expense items are translated using the average rate for the period. The translation adjustments are recorded in accumulated other comprehensive loss 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 remeasured 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. 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 periods: Year ended December 31, 2019 Balance sheet, except for equity accounts RMB 6.9630 to US$1.00 Income statement and cash flows RMB 6.9073 to US$1.00 Year ended December 31, 2020 Balance sheet, except for equity accounts RMB 6.5286 to US$1.00 Income statement and cash flows RMB 6.9032 to US$1.00
Intangible Assets	(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: Computer software 10 years
Impairment of Long-lived Assets	(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. Fair value is generally measured based on either quoted market prices, if available, or discounted cash flow analyses.
Revenue Recognition	(j) Revenue Recognition The Company recognizes revenues when its customer obtains control of promised goods or services, in an amount that reflects the consideration which it expects to receive in exchange for those goods. The Company recognizes revenues following the five step model prescribed under ASU No. 2014-09: (i) identify contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenues when (or as) we satisfy the performance obligation. Revenues from product sales are recognized when the customer obtains control of the Company's product, which occurs at a point in time, typically upon delivery to the customer. The Company expenses incremental costs of obtaining a contract as and when incurred if the expected amortization period of the asset that it would have recognized is one year or less or the amount is immaterial. Revenues from product sales are recorded net of reserves established for applicable discounts and allowances that are offered within contracts with the Company's customers. Product revenue reserves, which are classified as a reduction in product revenues, are generally characterized in the categories: discounts and returns. These reserves are based on estimates of the amounts earned or to be claimed on the related sales and are classified as reductions of accounts receivable as the amount is payable to the Company's customer.
Cost of Revenues	(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	(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. The significant uncertain tax position arose from the subsidies granted by the local government for the Company's PRC subsidiary, which may be modified or challenged by the central government or the tax authority. A reconciliation of January 1, 2019, through December 31, 2020 amount of unrecognized tax benefits excluding interest and penalties ("Gross UTB") is as follows: Gross UTB Surcharge Net UTB Balance as of January 1, 2019 $ 7,129,285 - 7,129,285 Decrease in unrecognized tax benefits taken in current period (86,703 ) - (86,703 ) Balance as of December 31, 2019 7,042,582 - 7,042,582 Increase in unrecognized tax benefits taken in current year 468,600 - 468,600 Balance as of December 31, 2020 $ 7,511,182 $ - $ 7,511,182 As of December 31, 2019 and 2020, the Company had not accrued any interest and penalties related to unrecognized tax benefits.
Research and Development and Advertising Expenses	(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 material costs for research and development.
Bills Payable	(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.
Warranties	(o) Warranties The Company provides a manufacturer's warranty on all its products. It accrues a warranty reserve for the products sold, which includes management's best estimate of the projected costs to repair or replace items under warranty. These estimates are based on actual claims incurred to date and an estimate of the nature, frequency and costs of future claims. These estimates are inherently uncertain given the Company's relatively short history of sales of its current products, and changes to its historical or projected warranty experience may cause material changes to the warranty reserve in the future.
Government Grants	(p) 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, interest expenses and removal costs. 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.
Share-based Compensation	(q) 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 remeasured 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 Postretirement Benefits	(r) Retirement and Other Postretirement 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	(s) Loss per Share Basic and diluted loss per share is computed by dividing net loss by the weighted average number of ordinary shares outstanding during the year.
Use of Estimates	(t) 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 revenue recognition, the recoverability of the carrying amount of long-lived assets, unrecognized tax benefits, impairment on inventories, valuation allowance for receivables and deferred tax assets, provision for warranty and sales returns, valuation of share-based compensation expense and warrants liability. Actual results could differ from those estimates.
Segment Reporting	(u) 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	(v) 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.
Warrant Liability	(w) Warrant Liability For warrants that are not indexed to the Company's stock, the Company records the fair value of the issued warrants as a liability at each balance sheet date and records changes in the estimated fair value as a non-cash gain or loss in the consolidated statement of operations and comprehensive income. The warrant liability is recognized in the balance sheet at the fair value (level 3). The fair value of these warrants has been determined using the Binomial model.
Recently Adopted Accounting Standards	Recently Adopted Accounting Standards In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement, which modifies the disclosure requirements for Level 1, Level 2 and Level 3 instruments in the fair value hierarchy. The guidance is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years, with early adoption permitted for any eliminated or modified disclosures. The Company applied the new standard beginning January 1, 2020.
Recently Issued Accounting Standards	Recently Issued Accounting Standards In May 2019, the Financial Accounting Standards Board ("FASB") issued ASU 2019-05, which is an update to ASU Update No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which introduced the expected credit losses methodology for the measurement of credit losses on financial assets measured at amortized cost basis, replacing the previous incurred loss methodology. The amendments in Update 2016-13 added Topic 326, Financial Instruments—Credit Losses, and made several consequential amendments to the Codification. Update 2016-13 also modified the accounting for available-for-sale debt securities, which must be individually assessed for credit losses when fair value is less than the amortized cost basis, in accordance with Subtopic 326-30, Financial Instruments— Credit Losses—Available-for-Sale Debt Securities. The amendments in this ASU address those stakeholders' concerns by providing an option to irrevocably elect the fair value option for certain financial assets previously measured at amortized cost basis. For those entities, the targeted transition relief will increase comparability of financial statement information by providing an option to align measurement methodologies for similar financial assets. Furthermore, the targeted transition relief also may reduce the costs for some entities to comply with the amendments in Update 2016-13 while still providing financial statement users with decision-useful information. ASU 2019-05 is effective for the Company for fiscal year beginning after December 15, 2022. The Company is currently evaluating the impact of this new standard on its condensed consolidated financial statements and related disclosures. In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes, which simplifies the accounting for income taxes, eliminates certain exceptions within ASC 740, Income Taxes, and clarifies certain aspects of the current guidance to promote consistent application among reporting entities. The guidance is effective for fiscal years beginning after December 15, 2020, and interim periods within those fiscal years, with early adoption permitted. Upon adoption, the Company must apply certain aspects of this standard retrospectively for all periods presented while other aspects are applied on a modified retrospective basis through a cumulative-effect adjustment to retained earnings as of the beginning of the fiscal year of adoption. The Company is evaluating the impact this update will have on its financial statements. In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848) (Topic 718): Improvemen20-04 contains practical expedients for reference rate reform related activities that impact debt, leases, derivatives and other contracts. The guidance in ASU 2020-04 is optional and may be elected over time as reference rate reform activities occur. The Company continues to evaluate the impact of the guidance and may apply the elections as applicable as changes in the market occur. In August 2020, the FASB issued ASU 2020-06, Debt - Debt with Conversion and Other Options (Subtopic 470- 20) and Derivatives and Hedging - Contracts in Entity's Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity's Own Equity ("ASU 2020-06"), which simplifies the accounting for certain financial instruments with characteristics of liabilities and equity. This ASU (1) simplifies the accounting for convertible debt instruments and convertible preferred stock by removing the existing guidance in ASC 470-20, Debt: Debt with Conversion and Other Options, that requires entities to account for beneficial conversion features and cash conversion features in equity, separately from the host convertible debt or preferred stock; (2) revises the scope exception from derivative accounting in ASC 815-40 for freestanding financial instruments and embedded features that are both indexed to the issuer's own stock and classified in stockholders' equity, by removing certain criteria required for equity classification; and (3) revises the guidance in ASC 260, Earnings Per Share, to require entities to calculate diluted earnings per share (EPS) for convertible instruments by using the if-converted method. In addition, entities must presume share settlement for purposes of calculating diluted EPS when an instrument may be settled in cash or shares. For SEC filers, excluding smaller reporting companies, ASU 2020-06 is effective for fiscal years beginning after December 15, 2021 including interim periods within those fiscal years. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020. For all other entities, ASU 2020-06 is effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. Entities should adopt the guidance as of the beginning of the fiscal year of adoption and cannot adopt the guidance in an interim reporting period. The Company is currently evaluating the impact that ASU 2020-06 may have on its condensed consolidated financial statements and related disclosures. 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.
