Item 1.  Security and Issuer

Pierce Avenue, Suite E, Louisville, Colorado 80027.

Item 2.  Identity and Background

(a) This Schedule 13D is being filed on behalf of (i) Bayerische Motoren Werke AG, a corporation organized under the laws of the Federal Republic of Germany (“BMW AG”); (ii) BMW INTEC Beteiligungs GmbH, a limited liability company organized under the laws of the Federal Republic of Germany and a wholly owned subsidiary of BMW AG (“BMW INTEC”); and (iii) BMW Holding B.V., a Dutch limited liability company and a wholly owned subsidiary of BMW INTEC (“BMW Holding” and, together with BMW AG and BMW INTEC, the “Reporting Persons”).
 
(b) The business address of BMW AG and BMW INTEC is Petuelring 130, 80809 Munich, Federal Republic of GermanyThe business address of BMW Holding is Einsteinlaan 5, 2289 CC Rijswijk, The Netherlands.  The principal business of BMW AG is the production of motor vehicles.  The principal business of each of BMW INTEC and BMW Holding is to serve as a holding company for business entities and investments.
 
The name, business address, citizenship and present principal occupation of each executive officer and each director of each Reporting Person are set forth on Schedule A hereto and are incorporated herein by reference.

(c) See Item 2(b).

(d) None of the Reporting Persons has, during the last five years, been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors).
 
(e) None of the Reporting Persons has, during the last five years, been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws, with the exception of the following:  In September 2020, BMW AG and two of its U.S. subsidiaries (the “BMW Entities”) entered into a settlement with the Securities and Exchange Commission (“SEC”) with respect to an investigation by the SEC into potential violations of U. S. securities laws by BMW Group relating to disclosures regarding BMW Group’s unit sales of new vehicles. The BMW Entities, without admitting or denying the allegations, consented to the entry of an order (the “SEC Order”) finding violations of Sections 17(a)(2) and 17(a)(3) of the U. S. Securities Act and agreed to pay a penalty of U. S.$18 million. The SEC Order alleged, among other things, that the disclosures that BMW Group had provided to investors in its U. S. bond offerings conducted under Rule 144A in the period from 2016 to 2019 had contained material misstatements and omissions regarding BMW Group’s U. S. retail vehicle deliveries.
 
(f) See Item 6 of the respective cover page of each Reporting Person.

The securities reported herein are held of record by BMW Holding.  BMW Holding is a wholly-owned subsidiary of BMW INTEC, which is a wholly-owned subsidiary of BMW AG.  Accordingly, BMW AG and BMW INTEC may also be deemed to indirectly beneficially own the securities reported herein.  This Schedule 13D does not include 1,144,393 shares of Common Stock held by a private investment vehicle (the “Private Fund”) managed by a manager that is not affiliated with the Reporting Persons, but in which BMW INTEC has economic interest as a limited partner.  In addition, an investment adviser that is wholly-owned by, but is operationally segregated from, BMW INTEC serves as an adviser to the manager of the Private Fund and may exercise investment or voting power with respect to the shares of Common Stock held by the Private Fund from time to time.  If the shares of Common Stock held by the Private Fund were deemed to be indirectly beneficially owned by BMW INTEC and BMW AG, such Reporting Persons would beneficially own 11,632,911 shares of Common Stock, representing 6.94% of the shares of Common Stock outstanding.

Each of the Reporting Persons disclaims beneficial ownership of the shares reported herein except to the extent of its pecuniary interest in such shares, and the inclusion of such securities in this report shall not be deemed an admission of beneficial ownership for any purpose.

Item 3.  Source and Amount of Funds or Other Consideration

The shares of Common Stock reported herein as being beneficially owned by the Reporting Persons were issued to BMW Holding on December 8, 2021 pursuant to  the business combination (the “Business Combination”) of the Company, DCRC Merger Sub Inc., a Delaware corporation and a wholly owned subsidiary of the Company (“Merger Sub”) and Solid Power Operating, Inc. (f.k.a. Solid Power, Inc.), a Colorado corporation  (“Solid Power Opco”).

Pursuant to the Business Combination, Merger Sub merged with and into Solid Power Opco, with Solid Power Opco surviving the merger as a wholly owned subsidiary of the Company (and Solid Power Opco changed its name to Solid Power Operating, Inc. and the Company changed its name to Solid Power, Inc.)  Pursuant to the Business Combination, BMW Holding received the shares of Common Stock reported herein as being beneficially owned by the Reporting Persons in exchange for an aggregate of 549,370 shares of common stock of Solid Power Opco and 2,746,853 shares of Series B Preferred Stock of Solid Power Opco.  BMW Holding purchased such securities from Solid Power Opco for an aggregate of $49.6 million.  All such securities were purchased using working capital of BMW Holding.  The shares of Common Stock described above as being held by the Private Fund were acquired pursuant to the closing of the Business Combination in exchange for an aggregate of 59,941 shares of common stock of Solid Power Opco and 299,707 shares of Series B Preferred Stock of Solid Power Opco, which were purchased by the Private Fund for an aggregate of $3 million using working capital of the Private Fund.

Item 4.  Purpose of Transaction

The Reporting Persons acquired the securities of the Company reported herein in connection with commercial arrangements entered into between Solid Power Opco and the Reporting Persons and/or their affiliates (“BMW Group”).  As previously disclosed by the Company, BMW Group and Solid Power Opco began working together in 2016, initially on all-solid-state battery cell research and development.  The relationship grew in 2017 to include efforts to jointly develop all-solid-state battery cell technology based on a joint development agreement of 1 July 2017, and further expanded in 2021 with amendments to the  joint development agreement dated February 18, 2021, March 22, 2021 and November 1, 2021 for automotive-scale EV cells for testing and vehicle integration with BMW of North America LLC. The shares of Series B Preferred Stock referenced above were purchased on May 5, 2021, at which time BMW Holding and Solid Power Opco also entered into a Board Nomination Support Agreement, dated May 5, 2021, pursuant to which Rainer Feurer, an executive within BMW Group, was appointed by BMW Holding to join the Solid Power Opco Board of Directors in May 2021.  BMW Holding’s director nomination rights survived the closing of the Business Combination, and Mr. Feurer now serves as a director of the Company.

The securities of the Company reported herein are held by the Reporting Persons for investment purposes.  The Reporting Persons intend to evaluate on an ongoing basis this investment in the Company and the Reporting Person’s options with respect to the investment.

The Reporting Persons may acquire additional shares of Common Stock and/or other securities of the Company from time to time or may dispose of any or all of such securities at any time.

From time to time, the Reporting Persons may engage in discussions with the Company’s Board of Directors and/or members of the Company’s management team concerning, without limitation, potential business combinations and strategic alternatives, the business, operations, capital structure, governance, management, strategy of the Company and other matters concerning the Company.

The Reporting Persons reserve the right to change their purpose and to formulate and implement plans or proposals with respect to the Company at any time and from time to time.  Any such action may be made by the Reporting Persons alone or in conjunction with other shareholders, potential acquirers, financing sources and/or other third parties and could include one or more purposes, plans or proposals that relate to or would result in actions required to be reported herein in accordance with Item 4 of Schedule 13D.

Item 5.  Interest in Securities of the Issuer

(a) and (b)  See Items 7-13 of the cover pages and Item 2 above.

(c)  The Reporting Persons did not engage in any transactions in securities of the Company during the sixty day period prior to the filing of this Schedule 13D, other than the receipt of the securities reported herein upon the consummation of the Business Combination, as discussed in Item 3.
