Solid Power develops and manufactures sulfide-based solid electrolyte materials for lithium-ion batteries, offering enhanced energy density, extended battery life, and superior safety compared to conventional liquid or gel electrolytes. Rather than building complete battery cells for sale, the company pursues a capital-efficient model by manufacturing and selling its electrolyte to Tier 1 battery manufacturers and automotive OEMs while also licensing cell manufacturing processes and designs, targeting primarily the battery electric vehicle market through partnerships with major OEMs including BMW, Samsung SDI, and SK On. Solid Power operates pilot manufacturing lines and produces solid-state cells of various sizes using multi-layered stacked pouch designs, positioning itself as the only entity operating both pilot-scale sulfide electrolyte manufacturing and pilot-scale cell manufacturing, which enables iterative development informed by internal cell feedback and customer requirements.
