Toyota, Idemitsu join hands to mass-produce all-solid-state batteries

Toyota Motor and Idemitsu Kosan have joined hands to develop and mass-produce all-solid-state batteries for electric vehicles, the companies said on Thursday. The partnership follows an announcement in June by Toyota, the world's biggest automaker by sales, that it would introduce the high-performance batteries to improve the driving range and reduce costs of future EVs in a strategic pivot. Idemitsu and Toyota said in a statement they would aim to commercialise the next-generation batteries in 2027-28, followed by full-scale mass production.
