About

Founded in 2023, Group1 is a private headquartered in Austin, United States with approximately 50-200 employees specializing in Energy Storage.

Group1 is building a potassium-ion battery platform derived from research lineage of Nobel Laureate John B. Goodenough, co-inventor of the lithium-ion battery. The company's potassium-ion chemistry eliminates dependence on scarce or geopolitically sensitive minerals like lithium, cobalt, and nickel. Products are drop-in compatible with existing 18650 format infrastructure and assembled into modular packs (KPack and KCabinet systems). Core applications target uninterruptible power supplies for data centers, defense/national security applications, grid energy storage systems, and compact robotics. The technology offers inherent safety advantages over lithium-ion, deep discharge capability, fire-safe properties, and is manufactured in the USA. Leadership includes battery scientists with combined experience spanning material development, commercialization, and scale-up across multiple technologies.
