Longer term, it is exploring a commercial-scale electrolyte facility in the Republic of Korea targeting up to 500 metric tons annually.
The company highlights deep partnerships with BMW Group, Samsung SDI, SK On, and Ford. In 2025 it signed a Joint Evaluation Agreement with Samsung SDI and BMW AG for all-solid-state batteries, advanced installation of an SK On pilot cell line, and continued electrolyte sampling to multiple potential customers and partners.
Solid Power remains pre-commercial and emphasizes development risk, reliance on government support, and competitive pressure. It notes a DOE grant of up to $50 million tied to a new continuous electrolyte line, balanced by a $60 million cost-share obligation.
