BASF Battery Materials, through its Chinese joint venture BASF Shanshan Battery Materials, has delivered its first batches of mass-produced cathode active materials for semi-solid-state batteries in collaboration with Beijing WELION New Energy Technology.
WELION New Energy develops solid-state battery technologies that are primarily used in EVs, energy storage, drones and power tools.
The companies have moved from concept to mass production in the year since they started the project in August 2024.
BASF Battery Materials has developed an ultra-high-nickel nickel cobalt manganese (NCM) cathode active material that has a composite coating layer to address interface issues between cathode materials and solid electrolytes. This enhances the energy density owing to higher capacity and lower resistance and improves the cycling performance and calendar life through suppressing side reactions.
“WELION will use BASF’s cathode materials in our new generation of semi-solid-state batteries and look forward to more joint projects both at home and globally,” said Dr. Jin Xiang, General Manager of WELION New Energy.
