Reports GanFeng's 500 Wh/kg solid-state cell and its context: the result exceeds the 350-400 Wh/kg range of leading NMC pouch cells and uses an oxide-electrolyte architecture the company has been developing since 2020. Automotive qualification for full solid-state production is expected 2028-2029. Notes Hyundai semi-solid deliveries beginning February 2026 as the first commercial revenue from GanFeng's solid-electrolyte programme.
