Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Operations	Note 1 - Organization and Operations alpha-En Corporation (the “Company”) was incorporated in Delaware on March 7, 1997. Since 2008, the focus of the Company’s business has been developing new technologies for manufacturing highly pure lithium metal, a raw material for use in lightweight, high energy density batteries, in an environmentally friendly manner for commercial purposes. In 2013, the Company invented a new process for the production of highly pure lithium metal and associated products at room temperature. The Company subsequently broadened its focus to develop products and processes derived from the Company’s new core proprietary technology, including battery components and compounds of lithium.

Going Concern and Liquidity

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Going Concern and Liquidity	Note 2 - Going Concern and Liquidity The Company’s condensed financial statements have been prepared assuming that it will continue as a going concern, which contemplates continuity of operations, realization of assets, and liquidation of liabilities in the normal course of business. As reflected in the condensed financial statements, the Company had an accumulated deficit of approximately $28.2 million at June 30, 2019, a net loss of approximately $2.6 million and approximately $740,000 net cash used in operating activities for the six months ended June 30, 2019. These factors raise substantial doubt about the Company’s ability to continue as a going concern. The Company is attempting to further develop the intellectual property associated with its technology; broaden its patent portfolio; scale up its production of various products; and begin generating revenue; however, the Company’s cash position is not sufficient to support its daily operations for the foreseeable future. The ability of the Company to continue as a going concern is dependent upon its ability to raise additional funds by way of a public or private offering and its ability to further develop its technology and generate sufficient revenue. While the Company believes in the viability of its technology and in its ability to raise additional funds by way of a public or private offering, there can be no assurances to that effect. The condensed financial statements do not include any adjustments related to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might be necessary should the Company be unable to continue as a going concern.

Accounting Policies [Abstract]
Significant and Critical Accounting Policies and Practices	Note 3 - Significant and Critical Accounting Policies and Practices Basis of Presentation and Principles of Consolidation The unaudited condensed balance sheet at December 31, 2018 was derived from audited annual financial statements but does not contain all of the footnote disclosures from the annual financial statements. The unaudited condensed financial statements have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) and reflect all adjustments (consisting of normal recurring adjustments unless otherwise indicated) which, in the opinion of management, are necessary for a fair presentation of the results for the interim periods presented. Certain information in footnote disclosures normally included in the financial statements prepared in conformity with accounting principles generally accepted in the United States of America have been condensed or omitted pursuant to the SEC rules and regulations for interim reporting. The financial results for the periods presented may not be indicative of the full year’s results. These unaudited condensed financial statements should be read in conjunction with the Company’s audited consolidated financial statements and the notes thereto for the fiscal year ended December 31, 2018 included in the Company’s Annual Report on Form 10-K filed on April 1, 2019. Use of Estimates The Company’s condensed financial statements include certain amounts that are based on management’s best estimates and judgments. The Company’s significant estimates include, but are not limited to, useful lives assigned to long-lived assets, fair value used in estimating the value of warrants, stock-based compensation, accrued expenses and provisions for income taxes. Due to the uncertainty inherent in such estimates, actual results may differ from these estimates. Restricted Cash The following is a summary of cash and restricted cash total as presented in the statements of cash flows for as of June 30, 2019 and 2018 (dollars are in thousands): As of June 30, 2019 2018 Cash $ 763 $ 1,089 Restricted cash - 15 Long-term deposit 35 35 Total cash and restricted cash $ 798 $ 1,139 Leases Effective January 1, 2019, the Company accounts for its leases under ASC 842, Leases. Under this guidance, arrangements meeting the definition of a lease are classified as operating or financing leases and are recorded on the consolidated balance sheet as both a right of use asset and lease liability, calculated by discounting fixed lease payments over the lease term at the rate implicit in the lease or the Company’s incremental borrowing rate. Lease liabilities are increased by interest and reduced by payments each period, and the right of use asset is amortized over the lease term. For operating leases, interest on the lease liability and the amortization of the right of use asset result in straight-line rent expense over the lease term. Variable lease expenses, if any, are recorded when incurred. In calculating the right of use asset and lease liability, the Company elects to combine lease and non-lease components. The Company excludes short-term leases having initial terms of 12 months or less from the new guidance as an accounting policy election and recognizes rent expense on a straight-line basis over the lease term. The Company continues to account for leases in the prior period financial statements under ASC Topic 840. Other than above, there have been no material changes in the Company’s significant accounting policies to those previously disclosed in the Company’s annual report on Form 10-K, which was filed with the SEC on April 1, 2019. Loss Per Share Basic loss per share of common stock is computed by dividing net loss attributable to common stockholders by the weighted average number of shares of common stock outstanding for the period. Diluted loss per share excludes the potential impact of common stock options, convertible preferred stock and outstanding common stock purchase warrants because their effect would be anti-dilutive. Securities that could potentially dilute loss per share in the future that were not included in the computation of diluted loss per share at June 30, 2019 and 2018 are as follows: As of June 30, 2019 2018 Warrants to purchase common stock 5,767,292 4,719,292 Options to purchase common stock 19,869,000 15,824,000 Preferred stock convertible into common stock 4,508,812 2,290,860 Total 30,145,104 22,834,152 Recent Accounting Pronouncements The Company considers the applicability and impact of all Accounting Standard Updates (“ASUs”). ASUs not discussed below were assessed and determined to be either not applicable or are expected to have minimal impact on our balance sheets or statements of operations. In July 2017, the FASB issued ASU 2017-11, Earnings Per Share (Topic 260), Distinguishing Liabilities from Equity (Topic 480) and Derivatives and Hedging (Topic 815): I. Accounting for Certain Financial Instruments with Down Round Features; II. Replacement of the Indefinite Deferral for Mandatorily Redeemable Financial Instruments of Certain Nonpublic Entities and Certain Mandatorily Redeemable Noncontrolling Interests with a Scope Exception In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) in order to increase transparency and comparability among organizations by, among other provisions, recognizing lease assets and lease liabilities on the balance sheet for those leases classified as operating leases under previous GAAP. For public companies, ASU 2016-02 is effective for fiscal years beginning after December 15, 2018 (including interim periods within those periods) using a modified retrospective approach and early adoption is permitted. In transition, entities may also elect a package of practical expedients that must be applied in its entirety to all leases commencing before the adoption date, unless the lease is modified, and permits entities to not reassess (a) the existence of a lease, (b) lease classification or (c) determination of initial direct costs, as of the adoption date, which effectively allows entities to carryforward accounting conclusions under previous U.S. GAAP. In July 2018, the FASB issued ASU 2018-11, Leases (Topic 842): Targeted Improvements, which provides entities an optional transition method to apply the guidance under Topic 842 as of the adoption date, rather than as of the earliest period presented. The Company adopted Topic 842 on January 1, 2019, using the optional transition method to apply the new guidance as of January 1, 2019, rather than as of the earliest period presented, and elected the package of practical expedients described above. Based on the analysis, on January 1, 2019, the Company recorded right of use assets of approximately $903,000, lease liability of approximately $1.0 million and eliminated deferred rent of approximately $115,000 (See Note 8). In June 2018, the FASB issued ASU 2018-07, Improvements to Nonemployee Share-Based Payment Accounting

Temporary Equity	Note 6 - Temporary Equity Series A Preferred Stock The following table summarizes the Company’s Series A Preferred Stock activities for the six months ended June 30, 2019 (dollars in thousands): Series A Preferred Stock Shares Amount Total Series A temporary equity as of December 31, 2018 4,208 $ 4,208 Accrued Series A Preferred Stock dividends 213 213 Total Series A temporary equity as of June 30, 2019 4,421 $ 4,421 As of June 30, 2019, the Company has 4,421 shares of Series A Preferred Stock convertible into 2,528,812 shares of common stock, and the dividends accrued and outstanding were $701,000 and reflected in carrying value of temporary equity. Series B Preferred Stock On April 16, 2019 the Company entered into a preferred stock purchase agreement (“Stock Purchase Agreement”) with several accredited and institutional investors (including certain executives and members of the Company’s Board of Directors), pursuant to which the Company agreed to issue and sell in a private placement up to 1,500 shares of its newly designated Series B Preferred Stock, par value $0.01 per share, as well as warrants to purchase the Company’s common stock, at a purchase price of $1,000 per unit, for total gross proceeds of up to $1.5 million. The Company has raised $970,000 from the issuance of 970 shares of Series B Preferred Stock and 970,000 warrants to purchase the Company’s common stock through June 30, 2019, including $50,000 advances from related parties converted into Series B Preferred Stock. Each share of Series B preferred stock is convertible in 2,000 shares of common stock and is redeemable by the Company at any time after the first anniversary. Upon liquidation of the Company, each share of Series B is entitled to receive a distribution of assets before any distribution to holders of common stock, and after satisfaction of all liabilities, in an amount equal to the original issuance price plus any accrued but unpaid dividends. The Series B preferred stock is entitled to cumulative non-compounding dividends at an annual rate of 10%, which are to be paid quarterly. At the Company’s election the dividend may be paid in either stock or cash. On the issuance date, the Company estimated the fair value of the warrants at $357,000 using the Black-Scholes option pricing model using the following primary assumptions: contractual term of 5.0 years, volatility rate of 71.9%, risk-free interest rate of 2.40% and expected dividend rate of 0%. Based on the warrant’s relative fair value to the fair value of the Series B Preferred Stock, approximately $214,000 of the $357,000 of aggregate fair value was allocated to the warrants, creating a corresponding preferred stock discount in the same amount. Due to the reduction of allocated proceeds to Series B Preferred Stock, the effective conversion price was approximately $0.39 per share creating a beneficial conversion feature of $505,000 which reduced the carrying value of the Series B Preferred Stock. Since the conversion option of the Series B Preferred Stock was immediately exercisable, the beneficial conversion feature was immediately accreted to preferred dividends, resulting in an increase in the carrying value of the Series B Preferred Stock. On April 8, 2019, in connection with the sale and issuance of the Series B Preferred Stock, the Company filed with the Secretary of State of the State of Delaware a certificate of designation establishing and designating the Series B Preferred Stock and the rights, preferences, privileges and limitations thereof. The following table summarizes the Company’s Series B Preferred Stock activities for the six months ended June 30, 2019 (dollars in thousands): Series B Preferred Stock Shares Amount Total Series B temporary equity as of December 31, 2018 - $ - Sale of Series B Preferred Stock 920 920 Conversion of advances into preferred stock 50 50 Beneficial conversion feature of Series B Preferred Stock - (505 ) Deemed dividends related to beneficial conversion feature of Series B Preferred Stock - 505 Accrued Series B Preferred Stock dividends 20 20 Deemed dividend on Series B Preferred Stock - 214 Fair Value of common stock warrant issued with Series B Preferred Stock - (214 ) Total Series B temporary equity as of June 30, 2019 990 $ 990 As of June 30, 2019, the Company has 990 shares of Series B Preferred Stock convertible into 1,980,000 shares of common stock, and the dividends accrued and outstanding were $20,000 and reflected in carrying value of temporary equity.

Equity [Abstract]
Stockholders' (Deficit) Equity	Note 7 - Stockholders’ (Deficit) Equity Stock Options The Company uses the Black-Scholes model to value stock options which requires certain assumptions. The fair value of the Company’s common stock was based upon the publicly quoted price on the date that the final approval of the awards was obtained. The Company does not expect to pay dividends in the foreseeable future so therefore the expected dividend yield is 0%. The expected term for stock options granted with service conditions represents the average period the stock options are expected to remain outstanding and is based on the expected term calculated using the approach prescribed by the Securities and Exchange Commission’s Staff Accounting Bulletin for “plain vanilla” options. The expected term for stock options granted with performance and/or market conditions represents the period estimated by management by which the performance conditions will be met. The Company obtained the risk-free interest rate from publicly available data published by the Federal Reserve. The Company uses a methodology in estimating its volatility percentage from a computation that was based on a comparison of average volatility rates of similar companies to a computation based on the standard deviation of the Company’s own underlying stock price’s daily logarithmic returns. The grant date fair value of stock options granted during the six months ended June 30, 2019 and 2018 was $771,000 and $8.0 million, respectively. The fair value of options granted during the six months ended June 30, 2019 and 2018 were estimated using the following weighted-average assumptions: For the Six Months Ended June 30, 2019 2018 Exercise price $ 0.25 $ 2.07 Expected stock price volatility 65 % 78 % Risk-free rate of interest 2.25 % 2.67 % Term (years) 3.1 4.0 A summary of option activity for employees and nonemployees under the Company’s stock option plan for the six months ended June 30, 2019 is presented below: Number of Shares Weighted Average Total Intrinsic Value Weighted Average Remaining Contractual Life (in years) Outstanding as of December 31, 2018 15,724,000 $ 1.60 $ 1,924,000 4.5 Granted 6,820,000 0.25 1,569,000 4.8 Cancelled (1,750,000 ) 1.90 - - Expired (925,000 ) 0.92 267,000 - Outstanding as of June 30, 2019 19,869,000 $ 1.14 $ 2,263,000 4.4 Options vested and expected to vest as of June 30, 2019 19,869,000 $ 1.14 $ 2,263,000 4.4 Options vested and exercisable as of June 30, 2019 7,279,000 $ 0.91 $ 989,000 2.9 Estimated future stock-based compensation expense relating to unvested stock options is approximately $6.7 million as of June 30, 2019 and will be amortized over 3.3 years.

For the six months ended June 30, 2019, there were approximately $1.6 million and $41,000 stock-based compensation expenses included in the general and administrative and research and development expense, respectively, compared to stock-based compensation expenses of $1.3 million and income resulted from stock-based compensation of $217,000 for the six months ended June 30, 2018, respectively.

Accounting Policies [Abstract]
Basis of Presentation and Principles of Consolidation	Basis of Presentation and Principles of Consolidation The condensed balance sheet at December 31, 2018 was derived from audited annual financial statements but does not contain all of the footnote disclosures from the annual financial statements. The unaudited condensed financial statements have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) and reflect all adjustments (consisting of normal recurring adjustments unless otherwise indicated) which, in the opinion of management, are necessary for a fair presentation of the results for the interim periods presented. Certain information in footnote disclosures normally included in the financial statements prepared in conformity with accounting principles generally accepted in the United States of America have been condensed or omitted pursuant to the SEC rules and regulations for interim reporting. The financial results for the periods presented may not be indicative of the full year’s results. These unaudited condensed financial statements should be read in conjunction with the Company’s audited consolidated financial statements and the notes thereto for the fiscal year ended December 31, 2018 included in the Company’s Annual Report on Form 10-K filed on April 1, 2019.
Use of Estimates	Use of Estimates The Company’s condensed financial statements include certain amounts that are based on management’s best estimates and judgments. The Company’s significant estimates include, but are not limited to, useful lives assigned to long-lived assets, fair value used in estimating the value of warrants, stock-based compensation, accrued expenses and provisions for income taxes. Due to the uncertainty inherent in such estimates, actual results may differ from these estimates.
Restricted Cash	Restricted Cash The following is a summary of cash and restricted cash total as presented in the statements of cash flows for as of June 30, 2019 and 2018 (dollars are in thousands): As of June 30, 2019 2018 Cash $ 763 $ 1,089 Restricted cash - 15 Long-term deposit 35 35 Total cash and restricted cash $ 798 $ 1,139
Leases	Leases Effective January 1, 2019, the Company accounts for its leases under ASC 842, Leases. Under this guidance, arrangements meeting the definition of a lease are classified as operating or financing leases and are recorded on the consolidated balance sheet as both a right of use asset and lease liability, calculated by discounting fixed lease payments over the lease term at the rate implicit in the lease or the Company’s incremental borrowing rate. Lease liabilities are increased by interest and reduced by payments each period, and the right of use asset is amortized over the lease term. For operating leases, interest on the lease liability and the amortization of the right of use asset result in straight-line rent expense over the lease term. Variable lease expenses, if any, are recorded when incurred. In calculating the right of use asset and lease liability, the Company elects to combine lease and non-lease components. The Company excludes short-term leases having initial terms of 12 months or less from the new guidance as an accounting policy election and recognizes rent expense on a straight-line basis over the lease term. The Company continues to account for leases in the prior period financial statements under ASC Topic 840. Other than above, there have been no material changes in the Company’s significant accounting policies to those previously disclosed in the Company’s annual report on Form 10-K, which was filed with the SEC on April 1, 2019.
Loss Per Share	Loss Per Share Basic loss per share of common stock is computed by dividing net loss attributable to common stockholders by the weighted average number of shares of common stock outstanding for the period. Diluted loss per share excludes the potential impact of common stock options, convertible preferred stock and outstanding common stock purchase warrants because their effect would be anti-dilutive. Securities that could potentially dilute loss per share in the future that were not included in the computation of diluted loss per share at June 30, 2019 and 2018 are as follows: As of June 30, 2019 2018 Warrants to purchase common stock 5,767,292 4,719,292 Options to purchase common stock 19,869,000 15,824,000 Preferred stock convertible into common stock 4,508,812 2,290,860 Total 30,145,104 22,834,152
Recent Accounting Pronouncements	Recent Accounting Pronouncements The Company considers the applicability and impact of all Accounting Standard Updates (“ASUs”). ASUs not discussed below were assessed and determined to be either not applicable or are expected to have minimal impact on our balance sheets or statements of operations. In July 2017, the FASB issued ASU 2017-11, Earnings Per Share (Topic 260), Distinguishing Liabilities from Equity (Topic 480) and Derivatives and Hedging (Topic 815): I. Accounting for Certain Financial Instruments with Down Round Features; II. Replacement of the Indefinite Deferral for Mandatorily Redeemable Financial Instruments of Certain Nonpublic Entities and Certain Mandatorily Redeemable Noncontrolling Interests with a Scope Exception In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) in order to increase transparency and comparability among organizations by, among other provisions, recognizing lease assets and lease liabilities on the balance sheet for those leases classified as operating leases under previous GAAP. For public companies, ASU 2016-02 is effective for fiscal years beginning after December 15, 2018 (including interim periods within those periods) using a modified retrospective approach and early adoption is permitted. In transition, entities may also elect a package of practical expedients that must be applied in its entirety to all leases commencing before the adoption date, unless the lease is modified, and permits entities to not reassess (a) the existence of a lease, (b) lease classification or (c) determination of initial direct costs, as of the adoption date, which effectively allows entities to carryforward accounting conclusions under previous U.S. GAAP. In July 2018, the FASB issued ASU 2018-11, Leases (Topic 842): Targeted Improvements, which provides entities an optional transition method to apply the guidance under Topic 842 as of the adoption date, rather than as of the earliest period presented. The Company adopted Topic 842 on January 1, 2019, using the optional transition method to apply the new guidance as of January 1, 2019, rather than as of the earliest period presented, and elected the package of practical expedients described above. Based on the analysis, on January 1, 2019, the Company recorded right of use assets of approximately $903,000, lease liability of approximately $1.0 million and eliminated deferred rent of approximately $115,000 (See Note 8). In June 2018, the FASB issued ASU 2018-07, Improvements to Nonemployee Share-Based Payment Accounting
