Toyota, the renowned manufacturer of the bZ4X electric crossover, has embarked on an unconventional partnership with Japanese petroleum firm Idemitsu to pioneer a mass-market solid-state battery, slated for deployment in forthcoming electric vehicles, commencing around 2027 or 2028. This unexpected union between the automotive and petroleum sectors was officially unveiled today.
Despite the intriguing irony of a petroleum company, responsible for oil platform operations, venturing into the domain of EV batteries, it is essential to highlight that Idemitsu has been actively engaged in sulfide solid electrolyte research since 2001. The company has already established a small pilot facility, which has continually expanded its output since its announcement in June.
