Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
Organization | Organization Aqua Metals, Inc. (the “Company”) was incorporated in Delaware and commenced operations on June 20, 2014 (inception). On January 27, 2015, the Company formed two wholly-owned subsidiaries, Aqua Metals Reno, Inc. (“AMR”) and Aqua Metals Operations, Inc. (collectively, the “Subsidiaries”), both incorporated in Delaware. The Company is engaged in the business of lead recycling through its patented and patent-pending AquaRefining ™ technology. Unlike smelting, AquaRefining is a room temperature, water-based process that emits less pollution than smelting, the traditional method of lead recycling. The Company built its first recycling facility in Nevada’s Tahoe Regional Industrial Complex (“TRIC”) in McCarran, Nevada and intends to pursue the development of additional lead acid battery recycling facilities based on the Company’s AquaRefining technology, likely through licensing or joint development arrangements. The Company commenced the shipment of products for sale, consisting of lead compounds and plastics, in April 2017, and through March 31, 2018, substantially all revenue was derived from the sale of lead compounds and plastics. In April 2018, the Company began shipping cast lead bullion (mixture of lead purchased to prime the kettles and AquaRefined lead from our AquaRefining process) blocks in addition to lead compounds and plastics and in June 2018, the Company began shipping high-purity lead from its AquaRefining process. In early 2019, the Company started the process of scaling its AquaRefining plant which includes the installation of equipment and the commissioning of AquaRefining modules. |

Accounting Policies [Abstract] | |
Summary of Significant Accounting Policies | Summary of Significant Accounting Policies The significant accounting policies and estimates used in preparation of the condensed consolidated financial statements are described in the Company’s audited consolidated financial statements as of and for the year ended December 31, 2018 , and the notes thereto, which are included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018 , as filed with the Securities and Exchange Commission, or the SEC, on February 28, 2019. There have been no material changes in the Company’s significant accounting policies during the three and six months ended June 30, 2019 except for the implementation of Accounting Standards Update (“ASU”) No. 2016-02, Leases, (“ASC 842”), as described below. Basis of presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) as found in the Accounting Standards Codification (“ASC”) and ASU of the Financial Accounting Standards Board (“FASB”) and pursuant to the rules and regulations of the SEC. Accordingly, they do not include all the information and footnotes required by such accounting principles for complete financial statements. In the opinion of management, all adjustments (which include normal recurring adjustments) considered necessary to present fairly each of the condensed consolidated balance sheet as of June 30, 2019 , the condensed consolidated statements of operations for the three and six months ended June 30, 2019 and June 30, 2018 , the condensed consolidated statements of stockholders' equity for the three and six months ended June 30, 2019 and June 30, 2018 and the condensed consolidated statements of cash flows for the six months ended June 30, 2019 and June 30, 2018 , as applicable, have been made. The condensed consolidated balance sheet as of December 31, 2018 has been derived from the Company’s audited financial statements as of such date, but it does not include all disclosures required by U.S. GAAP. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements for the period ended December 31, 2018 , which are included on Form 10-K filed with the Securities and Exchange Commission on February 28, 2019. The results of operations for the three and six months ended June 30, 2019 are not necessarily indicative of results that may be expected for the year ended December 31, 2019 . Principles of consolidation The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and its Subsidiaries, both of which are wholly-owned subsidiaries. Significant inter-company accounts and transactions have been eliminated in consolidation. Use of estimates The preparation of the condensed consolidated financial statements 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 condensed consolidated financial statements, and the reported amounts of expenses during the period. Significant items subject to such estimates and assumptions include the carrying amount and valuation of long-lived assets, the valuation of conversion features of convertible debt, valuation allowances for deferred tax assets, the determination of fair value of estimated asset retirement obligations, the determination of stock option expense and the determination of the fair value of stock warrants issued. Actual results could differ from those estimates. Net loss per share Basic net loss per share is computed by dividing net loss by the weighted average number of common shares outstanding during the period. Diluted net loss per share is computed by dividing the net loss by the weighted-average number of common share equivalents outstanding for the period determined using the treasury-stock method or the if-converted method, as applicable. For purposes of this calculation, stock options, restricted stock units (RSUs) and warrants to purchase common stock are considered to be common stock equivalents and are only included in the calculation of diluted net loss per share when their effect is dilutive. The following shares underlying outstanding convertible notes, stock options, RSUs and warrants to purchase common stock were antidilutive due to a net loss in the periods presented and, therefore, were excluded from the dilutive securities computation for the six months ended June 30, as indicated below. June 30, Excluded potentially dilutive securities (1): 2019 2018 Convertible note - principal — 702,247 Options to purchase common stock 3,604,001 1,583,354 Unvested restricted stock units 242,023 212,100 Financing warrants to purchase common stock 4,839,197 2,340,828 Total potential dilutive securities 8,685,221 4,838,529 (1) The number of shares is based on the maximum number of shares issuable on exercise or conversion of the related securities as of the period end. Such amounts have not been adjusted for the treasury stock method or weighted average outstanding calculations as required if the securities were dilutive. Segment and geographic information Operating segments are defined as components of an enterprise engaging in business activities for which discrete financial information is available and regularly reviewed by the chief operating decision maker in deciding how to allocate resources and in assessing performance. The chief operating decision maker views its operations and manages its business in one operating segment, and the Company operates in only one geographic segment. Concentration of credit risk Revenues from the following customers each represented at least 10% of total revenue for the three and six months ended June 30, 2019 and 2018 , respectively. They also represented a significant portion of our accounts receivable as of June 30, 2019 and December 31, 2018 , respectively.

Kay Metals 38 % — % 38 % — % 27 % — % Recently adopted accounting guidance In February 2016, the FASB issued ASU 2016-02 - Leases (ASC 842), which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e. lessees and lessors). The new standard requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase by the lessee. This classification will determine whether lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease, respectively. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. Leases with a term of 12 months or less will be accounted for similar to existing guidance for operating leases today. ASC 842 supersedes the previous leases standard, ASC 840 Leases. The standard has been adopted as of January 1, 2019. The new standard requires a modified retrospective transition approach for all leases existing at, or entered into after, the date of initial application, with an option to use certain transition relief. In July 2018, the FASB issued ASU No. 2018-11, Leases (Topic 842): Targeted Improvements, which amends ASC Topic 842 to provide another transition method, allowing a cumulative effect adjustment to the opening balance of retained earnings during the period of adoption. The Company has two longer term office leases and one equipment finance lease. The adoption of ASU 2016-02 on January 1, 2019 resulted in the recognition of right-of-use assets of approximately $1.6 million , lease liabilities for operating leases of approximately $1.8 million and no material impact to the Consolidated Balance Sheets and Consolidated Statements of Operations. See Note 9 for further information regarding the impact of the adoption of ASU 2016-02 on the Company's financial statements. Recent accounting pronouncements There were no other recent accounting pronouncements or changes in accounting pronouncements during the six months ended June 30, 2019 that are of significance or potential significance to the Company. |

Asset Retirement Obligation
Asset Retirement Obligation | 6 Months Ended |
Jun. 30, 2019 | |
Asset Retirement Obligation Disclosure [Abstract] | |
Asset Retirement Obligation | Asset Retirement Obligation The Company records a liability in the period in which an asset retirement obligation (ARO) is incurred, in an amount equal to the discounted estimated fair value of the obligation that is capitalized. In each subsequent fiscal quarter, this liability is accreted up to the final retirement cost. The determination of the ARO is based on an estimate of the future cost to remove and decontaminate the McCarran facility upon closure. The actual costs could be higher or lower than current estimates. The discounted estimated fair value of the closure costs is $0.7 million and the obligation was recorded as of March 31, 2017, when the obligation was deemed to have occurred. Offsetting this ARO is, as noted in Note 5 above, an asset retirement cost of the same amount that has been capitalized. The estimated fair value of the closure costs is based on vendor quotes to remove and decontaminate the McCarran facility in accordance with the Company’s closure plan as filed with the State of Nevada in its “Application for the Recycling of Hazardous Waste, by Written Determination” in 2016. Accretion of the ARO for the three and six months ended June 30, 2019 was approximately $11,000 and $23,000 , respectively. Accretion of the ARO for the three and six months ended June 30, 2018 was approximately $11,000 and $21,000 , respectively. The Company has entered into a facility closure trust agreement for the benefit of the Nevada Division of Environmental Protection (NDEP), an agency of the Nevada Division of Conservation and Natural Resources. Funds deposited in the trust are to be available, when and if needed, for potential decontamination and hazardous material cleanup in connection with the closure and/or post-closure care of the facility. The trustee will reimburse the Company or other persons as specified by the NDEP from the fund for closure and post-closure expenditures in such amounts as the NDEP shall direct in writing. Through June 30, 2019 , $670,000 has been contributed to the trust fund. |

Clarios (successor of Johnson Controls) Agreement Commitment Pursuant to the Clarios Investor Rights Agreement, the Company has agreed to compensate Clarios should either Stephen Clarke, the Company’s then current chief executive officer, or Selwyn Mould, the Company’s then current chief operating officer, no longer hold such positions or no longer devote substantially all of their business time and attention to the Company, whether as a result of resignation, death, disability or otherwise (such an event referred to as a “key-man event”). The Company has agreed to pay Clarios $1.0 million per occurrence, if either officer is subject to a key-man event during the 18 months following February 7, 2017. The Company also agreed to pay Clarios $1.0 million if either or both key-man events occur after 18 months and prior to 30 months following February 7, 2017. Pursuant to the agreement, if Clarios, in its sole and absolute discretion, agrees with the Company on mutually acceptable replacements for Dr. Clarke and/or Mr. Mould, as the case may be, the key-man penalties shall be deemed waived by Clarios. In connection with the resignations by Dr. Clarke and Mr. Mould described above, Clarios has submitted to the Company its claim for payment of the key-man penalties in the total amount of $2.0 million . We agreed to settle the Clarios Key-man penalty claim through our issuance of 807,436 shares of our common stock, which we issued in June 2019. Legal proceedings Beginning on December 15, 2017, three purported class action lawsuits were filed in the United Stated District Court for the Northern District California against the Company and certain of our former executive officers, Stephen Clarke, Thomas Murphy and Mark Weinswig. On March 23, 2018, the cases were consolidated under the caption In Re: Aqua Metals, Inc. Securities Litigation Case No 3:17-cv-7142. On May 23, 2018, the Court appointed lead plaintiffs and approved counsel for the lead plaintiffs. On July 20, 2018, the lead plaintiffs filed a consolidated amended complaint (“Amended Complaint”), on behalf of a class of persons who purchased the Company’s securities between May 19, 2016 and November 9, 2017, against the Company, Stephen Clarke, Thomas Murphy and Selwyn Mould. The Amended Complaint alleges the defendants made false and misleading statements concerning the Company’s lead recycling operations in violation of Section 10(b) of the Securities Exchange Act of 1934 (“Exchange Act”) and Rule 10b-5 promulgated thereunder. The Amended Complaint seeks to hold the individual defendants as control persons pursuant to Section 20(a) of the Exchange Act. The Amended Complaint also alleges a violation of Section 11 of the Securities Act of 1933 (“Securities Act”) based on alleged false and misleading statements concerning the Company’s lead recycling operations contained in, or incorporated by reference in, the Company’s Registration Statement on Form S-3 filed in connection with its November 2016 public offering. That claim is asserted on behalf of a class of persons who purchased shares pursuant to, or that are traceable to, that Registration Statement. The Amended Complaint seeks to hold the individual defendants liable as control persons pursuant to Section 15 of the Securities Act. The Amended Complaint seeks unspecified damages and plaintiffs’ attorneys’ fees and costs. On September 18, 2018, the defendants filed a motion to dismiss the Amended Complaint in its entirety and the plaintiff subsequently filed its opposition to the motion. In January 2019, the court notified the parties that it will rule on the motion to dismiss without a hearing. The Company denies that the claims in the Amended Complaint have any merit and it intends to vigorously defend the action. Beginning on February 2, 2018, five purported shareholder derivative actions were filed in the United States District Court for the District of Delaware against the Company and certain of its current and former executive officers and directors, Stephen Clarke, Selwyn Mould, Thomas Murphy, Mark Weinswig, Vincent DiVito, Mark Slade and Mark Stevenson. On May 3, 2018, the cases were consolidated under the caption In re Aqua Metals, Inc. Stockholder Derivative Litigation, Case No. 1:18-cv-201-LPS (D. Del.). The complaints were filed by persons claiming to be stockholders of Aqua Metals and generally allege that certain of the Company’s officers and directors breached their fiduciary duties to the Company by violating the federal securities laws and exposing the Company to possible financial liability. The complaints seek unspecified damages and plaintiffs’ attorneys’ fees and costs. The parties have entered into a stipulation staying the action until 30 days after a decision on the Company’s motion to dismiss the Amended Complaint in the class action described above. The Company denies that the claims in the shareholder derivative action have any merit and it intends to vigorously defend the action. The Company may, from time to time, be party to litigation and subject to claims incident to the ordinary course of business. As its growth continues, the Company may become party to an increasing number of litigation matters and claims. The outcome of litigation and claims cannot be predicted with certainty, and the resolution of any future matters could materially affect its future financial position, results of operations or cash flows. |

Accounting Policies [Abstract] | |
Basis of Presentation | Basis of presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) as found in the Accounting Standards Codification (“ASC”) and ASU of the Financial Accounting Standards Board (“FASB”) and pursuant to the rules and regulations of the SEC. Accordingly, they do not include all the information and footnotes required by such accounting principles for complete financial statements. In the opinion of management, all adjustments (which include normal recurring adjustments) considered necessary to present fairly each of the condensed consolidated balance sheet as of June 30, 2019 , the condensed consolidated statements of operations for the three and six months ended June 30, 2019 and June 30, 2018 , the condensed consolidated statements of stockholders' equity for the three and six months ended June 30, 2019 and June 30, 2018 and the condensed consolidated statements of cash flows for the six months ended June 30, 2019 and June 30, 2018 , as applicable, have been made. The condensed consolidated balance sheet as of December 31, 2018 has been derived from the Company’s audited financial statements as of such date, but it does not include all disclosures required by U.S. GAAP. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements for the period ended December 31, 2018 , which are included on Form 10-K filed with the Securities and Exchange Commission on February 28, 2019. The results of operations for the three and six months ended June 30, 2019 are not necessarily indicative of results that may be expected for the year ended December 31, 2019 |
Principles of consolidation | Principles of consolidation The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and its Subsidiaries, both of which are wholly-owned subsidiaries. Significant inter-company accounts and transactions have been eliminated in consolidation. |
Use of estimates | Use of estimates The preparation of the condensed consolidated financial statements 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 condensed consolidated financial statements, and the reported amounts of expenses during the period. Significant items subject to such estimates and assumptions include the carrying amount and valuation of long-lived assets, the valuation of conversion features of convertible debt, valuation allowances for deferred tax assets, the determination of fair value of estimated asset retirement obligations, the determination of stock option expense and the determination of the fair value of stock warrants issued. Actual results could differ from those estimates. |
Net loss per share | Net loss per share Basic net loss per share is computed by dividing net loss by the weighted average number of common shares outstanding during the period. Diluted net loss per share is computed by dividing the net loss by the weighted-average number of common share equivalents outstanding for the period determined using the treasury-stock method or the if-converted method, as applicable. For purposes of this calculation, stock options, restricted stock units (RSUs) and warrants to purchase common stock are considered to be common stock equivalents and are only included in the calculation of diluted net loss per share when their effect is dilutive. |
Segment and geographic information | Segment and geographic information Operating segments are defined as components of an enterprise engaging in business activities for which discrete financial information is available and regularly reviewed by the chief operating decision maker in deciding how to allocate resources and in assessing performance. The chief operating decision maker views its operations and manages its business in one operating segment, and the Company operates in only one geographic segment. |
Concentration of credit risk | Concentration of credit risk Revenues from the following customers each represented at least 10% of total revenue for the three and six months ended June 30, 2019 and 2018 , respectively.

Recent accounting pronouncements | Recently adopted accounting guidance In February 2016, the FASB issued ASU 2016-02 - Leases (ASC 842), which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e. lessees and lessors). The new standard requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase by the lessee. This classification will determine whether lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease, respectively. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. Leases with a term of 12 months or less will be accounted for similar to existing guidance for operating leases today. ASC 842 supersedes the previous leases standard, ASC 840 Leases. The standard has been adopted as of January 1, 2019. The new standard requires a modified retrospective transition approach for all leases existing at, or entered into after, the date of initial application, with an option to use certain transition relief. In July 2018, the FASB issued ASU No. 2018-11, Leases (Topic 842): Targeted Improvements, which amends ASC Topic 842 to provide another transition method, allowing a cumulative effect adjustment to the opening balance of retained earnings during the period of adoption. The Company has two longer term office leases and one equipment finance lease. The adoption of ASU 2016-02 on January 1, 2019 resulted in the recognition of right-of-use assets of approximately $1.6 million , lease liabilities for operating leases of approximately $1.8 million and no material impact to the Consolidated Balance Sheets and Consolidated Statements of Operations. See Note 9 for further information regarding the impact of the adoption of ASU 2016-02 on the Company's financial statements. Recent accounting pronouncements There were no other recent accounting pronouncements or changes in accounting pronouncements during the six months ended June 30, 2019 that are of significance or potential significance to the Company. |
