Large Pilot Solid Electrolyte Facility

Chiyoda is conducting the basic design for a large pilot solid electrolyte production facility for Idemitsu Kosan Co., Ltd. (Idemitsu) in their Chiba Complex, with the goal of commercializing all-solid-state batteries.

Solid electrolyte is a key material for all-solid-state batteries, which contribute to carbon neutrality through the evolution of electric vehicles and the establishment of a resource-circulating society.

Idemitsu will undertake the facility for solid electrolytes, derived from sulfur (a byproduct of petroleum) developed by Idemitsu over many years of research, in all-solid-state lithium-ion rechargeable batteries, under a project selected by NEDO’s ‘Green Innovation Fund Projects/Development of Next-Generation Storage Batteries and Motor Development’. 
The facility will accelerate Idemitsu’s mass-production technology for solid-state electrolytes and contribute to the early launch of the all-solid-state battery market.

Chiyoda continues to contribute to the social implementation of all-solid-state battery technology through this project.
