Associated PressTOKYO — Japan’s top automaker Toyota agreed Thursday to work with Idemitsu, a major Japanese oil company, on technology for mass production of solid-state batteries that promise to be a key component in future electric vehicles. Toyota, with its production finesse, and Idemitsu, which owns technologies in materials, said they are aiming for successful commercialization of all-solid-state batteries in 2027 or 2028, followed by full-scale mass production.
