BASF Battery Materials has delivered its first batch of solid-state battery materials through its China-headquartered joint venture BASF Shanshan Battery Materials.
The first batches of mass-produced cathode active materials (CAM) were delivered by the firm in collaboration with Chinese company WeLion New Energy Technology. The milestone comes a year after the companies began a project to develop materials for the lithium-ion technology.
WeLion New Energy develops batteries for electric vehicle and energy storage applications as well as drones and power tools.
BASF Shanshan Battery Materials’ (BSBM) has developed an ultra-high nickel NCM (Nickel Cobalt Manganese) cathode active material. The company says its composite coating layer addresses interface issues between CAM and solid electrolytes.
According to the company, material enhances the energy density and improves cyclability and calendar life through suppressing side reactions in interfaces between CAM and electrolyte.
WeLion will use German-headquartered BASF’s cathode materials in its new generation of semi-solid-state batteries. WeLion’s semi-solid-state battery cells have an energy density of up to 350Wh/kg
WeLion’s semi-solid-state battery cells combine solid materials with a reduced amount of liquid electrolyte. It’s cells use an ultra-thin metallic lithium foil to increase energy density, and an ionic conductive separator to improve ionic conductivity.
The material manufacturing milestone reflects the shared commitment of WeLion New Energy and BASF to bring to market the large-scale industrialisation of next-generation battery technologies.
