Umicore, a materials technology and recycling company, and oil company Idemitsu Kosan have reached an agreement to co-develop catholyte materials, which integrate cathode active materials (CAM) with solid electrolytes, for all-solid-state battery applications. Since Umicore began work on CAMs for solid-state batteries in 2017, it has established some patents in the area.

“Based on more than 20 years of experience, Idemitsu has developed the technology of sulfide solid electrolytes and holds many patents related to sulfide solid electrolytes,” says Idemitsu Managing Executive Officer Hajime Nakamoto.

“Idemitsu Kosan has an established method for manufacturing high-purity lithium sulfide,” according to Umicore.
