Samsung SDI, BMW and US battery technology company Solid Power have signed an agreement to work together on establishing global value chains for all-solid-state batteries across materials, cells and EVs.

The collaboration aims to pave the way for the commercialization of all-solid-state battery cells by bringing together their complementary expertise in cell manufacturing, automaking and materials development.

Under the partnership, Samsung SDI will supply battery cells using the solid electrolyte developed by Solid Power. BMW will develop modules and packs for the cells. The three companies aim to evaluate the performance of the cells based on the agreed parameters and requirements and to integrate them into BMW’s next-generation evaluation vehicles.

Samsung SDI and BMW have collaborated since 2009, when the German automotive group chose the South Korean firm as a battery supplier. In March 2023, Samsung SDI established a pilot line at the Suwon R&D Center in South Korea, and it began producing prototypes at the end of 2023. Sample tests are currently underway in collaboration with multiple customers. The battery developer outlined its roadmap for mass production of all-solid-state batteries last year. It plans to mass-produce 900 Wh/L solid-state batteries using its solid electrolyte and anode-less technologies.

“Our solid electrolyte technology is designed for stability and conductivity, and by working closely with global leaders in automotive and battery innovation, we strive to bring ASSB technology closer to widespread adoption,” said John Van Scoter, President and CEO of Solid Power.
