TOKYO — As solid-state batteries move closer to broad use in electric cars and other equipment, some Japanese companies will make a bid for early-mover advantage in the emerging field of testing these next-generation power sources.
Nippon Steel Technology, a unit of Japan’s top steelmaker, plans to launch by March 2023 a testing service at its Amagasaki development center near Osaka. Unusually for such a service, this will extend as far as building prototypes based on designs provided by battery makers.
