Solid Power is a pre-commercial U.S. company developing sulfide-based solid electrolyte materials for solid-state batteries, targeting the EV market. Its core product is a powder-form sulfide electrolyte that replaces the liquid electrolyte in conventional lithium-ion batteries, with the goal of delivering better energy density, battery life, and safety. Solid Power does not plan to manufacture battery cells commercially. Instead, the company sells electrolyte material to battery manufacturers and OEMs and licenses its cell designs and manufacturing processes — a capital-light model that avoids the billions in investment required to build cell gigafactories. Key customers and partners include SK On, Samsung SDI, BMW, and Ford. Solid Power currently operates two pilot electrolyte manufacturing lines for customer sampling and internal development, and is building a third continuous-process line expected to be commissioned by end of 2026. Revenue today comes from milestone-based partner agreements, DOE grant reimbursements, and small-volume electrolyte sampling sales. The long-term model targets recurring, volume-based electrolyte sales once solid-state cells reach commercial production, which management expects could begin for some customers in 2027–2028, with meaningful scale around 2030 and beyond. The company is pre-revenue at scale and relies on its balance sheet and capital raises to fund operations until commercialization.
