Battery milestone for BASF

Together with Welion New Energy Technology, China-based BASF Battery Materials has delivered its first batches of mass-produced cathode active materials (CAMs) for semi-solid-state batteries. The company described this as a “significant step” towards industrialising these batteries, which some see as next generation of battery technology.

The project began in August 2024 and resulted in the development of an ultra-high nickel NCM (nickel cobalt manganese) CAM with a composite coating layer to address interface issues between the material and the solid electrolytes. “This not only enhances the energy density by higher capacity and lower resistance but also improves the cycling performance and calendar life through suppressing side reactions in interfaces between CAM and electrolyte,” BASF said.
