Geely to challenge EV rivals with 400 Wh/kg solid-state battery testing

Geely is advancing its solid-state battery technology from laboratory research to real-world application, aiming to complete its first fully integrated all-solid-state battery pack by 2026. This battery pack will then be installed in a test vehicle for performance validation under actual operating conditions, marking a significant step toward future production. The company has consolidated its battery operations under Zhejiang Jiyao Tongxing Energy Technology in 2025, enabling integrated development of battery cells and safety systems. One early product from this effort is the Aegis Short Blade lithium iron phosphate (LFP) battery, with 20 ampere-hour engineering samples already produced. Geely’s experimental solid-state cells reportedly achieve energy densities around 400 Wh/kg, with ongoing testing of various electrolyte materials, including sulfide- and oxide-based types. The broader solid-state battery industry in China is transitioning from fundamental research to full battery pack assembly, vehicle integration, and on-road testing, with some projects entering pilot production.
