BASF Battery Materials, through its joint venture BASF Shanshan Battery Materials Co., Ltd. (BSBM), has delivered its first mass-produced cathode active materials (CAM) designed for Semi-Solid-State batteries to Beijing WELION New Energy Technology Co., Ltd. This milestone reflects a year of close collaboration aimed at industrializing next-generation solid-state battery technology.
Solid-state batteries are expected to offer higher energy density and improved safety compared with traditional lithium-ion cells. Since launching the project in August 2024, BSBM and WELION New Energy have advanced from concept to pilot-scale production in just 12 months. The breakthrough centers on an ultra-high nickel NCM (nickel-cobalt-manganese) CAM featuring a proprietary composite coating layer that addresses interface stability between the cathode material and solid electrolytes. This innovation reduces internal resistance, boosts capacity, suppresses side reactions, and enhances both cycling performance and calendar life.
“Reaching commercial production so rapidly underscores our combined technical expertise and seamless teamwork,” said Dr. Xin Xia, Chief Technology Officer of BSBM. “Our shared commitment to scientific rigor and agile development has been key to achieving this delivery milestone,” added Dr. Wenjun Li, Director of the WELION New Energy Engineering Institute.
Dr. Jin Xiang, General Manager of WELION New Energy, commented, “We are impressed with BASF’s robust technology and responsiveness. Integrating their cathode materials into our Semi-Solid-State battery platform sets the stage for future joint projects both domestically and internationally.”
Desmond Long, Senior Vice President of BASF Battery Materials and CEO of BSBM, noted, “This collaboration marks a significant step forward for solid-state battery commercialization. We look forward to deepening our partnership with WELION New Energy to drive further breakthroughs.”
By combining WELION’s 40 years of solid‐state battery research with BASF’s two decades of CAM development, the two companies are advancing safer, more energy-dense solutions for electric vehicles, energy storage, and other markets. The successful delivery of these materials underscores their shared vision to accelerate the large-scale deployment of next-generation battery technologies.
