Toyota is nearing mass production of solid-state batteries. In October 2023, Toyota announced a partnership with Idemitsu Kosan, Japan’s second-largest oil refiner, to mass-produce solid-state batteries by 2027-2028. The two companies plan to build a large pilot facility to produce sulfide solid electrolytes, which are key materials in solid-state batteries.
Toyota has been working on solid-state batteries for over a decade, and it holds more than 1,000 patents related to this technology. The company has made significant progress in recent years, and it is now one of the leaders in the development of solid-state batteries.
Solid-state batteries offer several advantages over traditional lithium-ion batteries, including higher energy density, faster charging times, and better safety. If Toyota is able to mass-produce solid-state batteries at scale, it could give the company a significant advantage in the electric vehicle market.
However, there are still some challenges that need to be addressed before solid-state batteries can be mass-produced. One challenge is the cost of the materials used in solid-state batteries. Another challenge is the manufacturing process, which is more complex than the manufacturing process for traditional lithium-ion batteries.
Despite these challenges, Toyota is confident that it can mass-produce solid-state batteries by 2027-2028. If the company is successful, it could revolutionize the electric vehicle market.
