BASF granted usage license for Vinylene Carbonate in lithium-ion batteries from Mitsubishi

BASF and Mitsubishi Chemical Corporation have announced the signing of aroyalty-bearinglicensing agreement that grants BASF usage rights forVinyleneC arbonate based on Mitsubishi Chemical’s proprietary patents. Vinylene Carbonateisa key ingredient in BASF’s electrolyte formulations, which are used by cell manufacturers in the production of lithium-ion batteries. Additionally, the agreement provides BASF with the right to grant sub-licenses to cell manufacturersthat use electrolyte formulations made by BASF or Mitsubishi Chemical.

The agreement constitutes the successful transfer of a licensing arrangement previously established between Mitsubishi Chemical and the electrolytes business of German chemical and pharmaceutical company Merck. BASF recently acquired Merck’s electrolyte activities, which are now part of BASF’s global Battery Materials business.

Electrolytes are complex formulations that ensure the transport of the electric charge inside the battery. High-quality electrolytes can provide essential prerequisites for raising battery performance. Vinylene Carbonate is an important performance additive that ensures the efficient long-term stability of lithium-ion battery cells.

"This license from Mitsubishi Chemical Corporation adds to our already strong battery materials technology and intellectual property portfolio, supporting our market activities and our long-term objective of becoming the leading provider of functional materials and components to serve cell and battery manufacturers worldwide," said Ralf Meixner, Senior Vice President of BASF’s Global Battery Materials Business.

Innovative materials and functional components are prerequisites for safe, efficient and affordable electromobility. Together with partners in industry and science, BASF is developing materials and technologies for today’s and next generation lithium-ion batteries, as well as future battery systems.

"The license granted to BASF is one of our strategic achievements leveraging our intellectual property, said Mr. Yoshitaka Araki, General Manager of Mitsubishi Chemical’s Battery Materials Department. "Mitsubishi Chemical has granted the Vinylene Carbonate license to some valued customers who wish to achieve critical battery performance. With our advanced research capabilities we will continue strengthening our leading position in the industry."

Mitsubishi Chemical has more than 20 years of experience in the formulated electrolyte business since the inception of the lithium-ion battery industry. Mitsubishi Chemical has established manufacturing sites for formulated electrolytes in North America, Europe and China, where the growth of automotive applications is anticipated.
