Thought leaders for battery materials
Asahi Kasei is a pioneer in the field of modern battery technology. Our foundation was established by Asahi Kasei researcher Dr. Akira Yoshino and his development of the first working prototype of the lithium-ion battery in 1983.
Today, the company is a market-leading supplier of lithium-ion battery separators, as well as engineering plastics and foams. These materials significantly contribute to the safety, performance, and size of the battery pack for electric vehicles.
