Solid-state battery specialist Solid Power, Inc. has announced it has deepened its partnership with the BMW Group.

Under an expanded Joint Development Agreement, Solid Power has granted the BMW Group a research and development licence to Solid Power’s all-solid-state cell design and manufacturing know-how.

Solid Power says the broadened relationship provides significant benefits to both companies, including conducting complementary cell development and manufacturing activities at both Solid Power and the BMW Group to further advance the capability of Solid Power’s technology.

The BMW Group intends to duplicate Solid Power’s pilot production lines at its own facility in Germany and produce prototype cells based on Solid Power’s proprietary technology. Prior to the installation of the BMW Group’s prototype line, the BMW Group’s personnel will work hand-in-hand at Solid Power’s facilities to optimize cell manufacturing processes.

The BMW Group has agreed to pay Solid Power $20 million through June 2024, subject to achieving certain milestones. The expanded Joint Development Agreement includes sharing of proprietary all-solid-state electrode and cell manufacturing know-how but does not include a license to intellectual property related to Solid Power’s electrolyte material, which remains its core business. Once the BMW Group installs its prototype production line, Solid Power expects to supply its electrolyte material to the BMW Group for prototype cell production.

“We could not be more excited about growing our relationship with BMW, a company that has demonstrated a strong commitment to Solid Power’s technology for the past seven years,” said Dr. Derek Johnson, Chief Operating Officer of Solid Power. “We believe this expanded partnership and increased collaboration is an added vote of confidence in Solid Power’s technology development.”

“BMW remains committed to the pursuit of all-solid-state batteries, a technology which we believe has significant potential for the future,” said Frank Weber, Member of the Board of Management BMW AG, Development. “We look forward to working even more closely with Solid Power and adding the capability to produce solid-state cells based on Solid Power’s designs at our own pilot facility. We expect this agreement to accelerate the installation of our solid-state prototype line and our companies’ mutual goal of commercializing this promising cell technology.”

“Expanding our relationship with BMW is further evidence that both companies believe Solid Power is on the right track with its technology development,” said David Jansen, Interim CEO, President and Chair of Solid Power. “I am encouraged by the progress our team continues to make toward achieving our company’s goals. Over the past several months, we began delivering 20 Ah cells to our partners, including BMW, for initial testing and commenced production of our initial EV cells. We look forward to bringing our electrolyte manufacturing facility online and commencing the formal automotive qualification process.”
