Enflow

Enflow is a South Korean developer of sulfide-based solid electrolyte materials for all-solid-state batteries (ASSB), with a focus on electric vehicle applications. The company has pioneered a proprietary vapor thermal spray process to mass-produce spherical fine-powder sulfide electrolytes — a first-in-class manufacturing approach that enables high-density packing, a critical factor in ASSB commercialization. Headquartered in Osan, Gyeonggi-do, Enflow conducts research and production in partnership with leading domestic companies and was constructing a solid electrolyte plant in Cheonan, South Korea as of April 2026.
