The start of the pilot production phase of all-solid-state battery packs was also announced at the time.The company is pursuing two parallel solid-state battery technology routes based on silicon-carbon and lithium-metal anodes. Ganfeng sees lithium-metal technology as a key route to higher energy density and faster commercialisation of next-generation batteries for electric vehicles and aviation applications. At the same time, the company is expanding its silicon-based battery portfolio with products offering energy densities ranging from 320 to 480 Wh/kg. According to Ganfeng, its 320 Wh/kg battery has already exceeded 1,000 charging cycles, while development of the 480 Wh/kg version is still ongoing.The different battery configurations are intended to address varying requirements for energy density, durability and application scenarios. Ganfeng identified premium electric vehicles, drones, eVTOL aircraft, robotics and consumer electronics as target markets.Ganfeng has long been one of the world’s largest lithium processors and supplies companies, such as Hyundai and Changan. It also works with Dongfeng. The latter has begun extreme-cold testing of vehicles equipped with 350 Wh/kg solid-state batteries, while Changan plans to start trial installations of 400 Wh/kg solid-state batteries during 2026.carnewschina.com, cnevpost.com
