BASF Delivers First CAM for Semi-Solid-State Batteries to WELION

Project Milestone

BASF Battery Materials, through its joint venture BASF Shanshan Battery Materials Co., Ltd. (BSBM), has reached a significant milestone in next-generation battery technology. In collaboration with Beijing WELION New Energy Technology Co., Ltd., BASF has delivered its first batches of mass-produced Cathode Active Materials (CAM) for Semi-Solid-State batteries, marking a step towards industrializing Solid-State batteries.

Technological Advancements

The rapid development of the new energy industry demands higher energy density and enhanced safety from batteries. Solid-State batteries, including Semi-Solid-State variants, are viewed as the next generation of battery technology. BSBM developed an ultra-high Nickel NCM (Nickel Cobalt Manganese) cathode active material with a unique composite coating layer to address interface issues between CAM and solid electrolytes, enhancing energy density and cycling performance.

Collaboration and Expertise

WELION New Energy, with over 40 years of experience in Solid-State battery technologies, primarily serves electric vehicles, energy storage, and other applications. BSBM, with over two decades of expertise in cathode active materials, contributes to handling critical challenges of Solid-State batteries. The project, initiated in August 2024, moved swiftly from concept to mass production in just one year through seamless teamwork and a shared commitment to technological advancement.

Future Prospects

This collaboration reflects the shared commitment of WELION New Energy and BASF to accelerate the development, commercialization, and large-scale industrialization of next-generation battery technologies. By combining WELION’s expertise in Solid-State Batteries with BASF’s materials innovation, both companies aim to drive progress toward safer, more energy-dense solutions.
