Group1 develops potassium‑ion battery (KIB) technology and commercially produced potassium cathode material Kristonite™ (Potassium Prussian White, KPW), a 4V cathode designed for KIBs. The company says Kristonite™ enables faster charging, enhanced safety, and higher energy density versus LFP‑based lithium‑ion and sodium‑ion batteries. Led by CEO and co‑founder Alex Girau and CPO and co‑founder Leigang Xue, Group1 intends to scale production of its potassium cathode material and commercially produce KIBs to support domestic manufacturing and U.S. energy security. The company is pursuing partnerships with Tier‑1 cell and automotive manufacturers and is in early engagement with supply‑chain partners and several large cell manufacturers, domestic and global. Group1 has raised $7.5M to date to bring KIB technology to market and is positioning Kristonite™ as a lithium‑alternative solution.
