BASF Delivers Initial Cathode Materials for Semi-Solid State Battery Production

Beijing Welion New Energy Taps BASF for Next-Gen Battery Materials

Beijing Welion New Energy Technology, a pioneer in solid-state lithium-ion battery technology, has taken a significant step forward in its mission to revolutionize the battery industry. The Chinese battery developer has received its first batch of mass-produced cathode materials for semi-solid state batteries from German chemical company BASF.

This collaboration, which was launched in August 2024, transitioned from the concept phase to series production within a year. The project aims to address interface issues between the cathode material and the solid electrolyte, a common challenge in the production of solid-state batteries.

BASF's cathode materials are based on a high-nickel NCM (Nickel Manganese Cobalt) cathode material with a special composite coating. This development is said to promise enhancements in energy density, cycle stability, and service life, making it a valuable asset for Welion's next-generation batteries.

Welion New Energy, founded in 2016, specializes in researching, developing, and producing solid-state lithium-ion batteries. The company has achieved several technological firsts and describes itself as a pioneer in the field.

The joint projects between BASF and Welion New Energy are not limited to the production of cathode materials. They may also involve research and development activities, with the ultimate goal of bringing these innovative materials to the market for commercial use.

Welion New Energy has close ties to the Institute of Physics at the Chinese Academy of Sciences, further strengthening its position as a leader in the solid-state battery sector. However, the name of the leader of Welion New Energy Technology remains undisclosed in the search results.

This collaboration marks an important milestone in the advancement of solid-state battery technology, with potential implications for various industries that rely on batteries for power, such as electric vehicles and renewable energy storage systems. As Welion and BASF continue their joint projects, the future of battery technology looks promising.
