Toyota and the Japanese oil enterprise Idemitsu Kosan announced plans to work together to mass-produce solid-state batteries for electric vehicles. These batteries will be able to reduce EV charging times and support longer driving ranges, according to Investopedia.

“With repeated efforts involving trial and error, we have succeeded in developing a material that is more stable and less prone to crack,” Toyota’s chief executive officer, Koji Sato, told reporters in Tokyo. “The future of mobility lies in the tie-up between the auto and energy sectors, including this innovation hailing from Japan.”

This comes months after Toyota claimed that it would be shifting towards using solid-state batteries after working on the technology for over a decade. Idemitsu said that it has been working on solid-state battery R&D since 2001.

Toyota and Idemitsu said they will be setting up a supply chain for the solid electrolytes necessary for the “commercialization” of solid-state batteries, with plans to produce batteries for EVs starting between 2027 and 2028.

Toyota shares were up by 2% in early trading at 9:45 a.m. EDT on October 12. Toyota’s stock has grown by more than 31% year-to-date.
