With the help of relevant specialist knowledge, the cooperation has set itself the goal of nothing less than a technological breakthrough.
Umicore brings to the collaboration its experience in a wide range of cathode active materials for lithium-ion batteries, and Idemitsu Kosan its know-how in the field of solid electrolytes.
Umicore has been working on solid-state CAM chemistry since 2017. The company owns several key patents in this technology area. In 2017, Umicore acquired three nickel-manganese-cobalt patent families for cathode materials from 3M. In May 2021 the company entered into a patent cross-licensing agreement with BASF covering a wide range of cathode materials and precursors. The agreement covers more than 100 patent families.
Idemitsu Kosan has a well-established high-purity lithium sulfide production process developed in the petrochemical business, and has numerous patents for sulfide solid electrolytes using lithium sulfide as raw material.
