Stardust Power is a development-stage refinery company that processes lithium chloride feedstocks from multiple sources—including oilfield brines, salt flats, and geothermal brines—into battery-grade lithium carbonate (BGLC) for use in lithium-ion batteries, energy storage systems, and defense applications. Operating as a midstream participant in the battery supply chain, the company is building a refinery in Oklahoma designed to convert multiple feedstock types into BGLC, reducing dependency on any single source and leveraging lower-carbon brine-based processing compared to hard-rock or clay extraction methods. The company generates revenue by selling BGLC to battery manufacturers, electric vehicle OEMs, and defense contractors, while funding its operations through equity offerings, convertible debt, and government incentives aimed at developing domestic battery material production capacity.
