In a pivotal move for the electric vehicle (EV) industry, Japan’s leading automaker, Toyota, has entered into a collaboration with Idemitsu, a Japanese oil company. Their collective goal is the advancement and mass production of solid-state batteries, projected to be a cornerstone in the future of EVs.
Solid-state batteries are viewed as essential for the large-scale commercialization of electric vehicles. They offer enhanced stability and potential power over the lithium-ion batteries that are mainly used in current EVs. Toyota and Idemitsu are targeting the commercial release of all-solid-state batteries in the years 2027 or 2028, followed closely by their full-scale mass production.
Both companies are seasoned veterans in the realm of solid-state battery research. Idemitsu embarked on its research journey in 2001, while Toyota began its efforts in 2006. Their collaboration is specifically concentrating on the development of sulfide solid electrolytes, malleable, adhesive materials that are suitable for mass production.
The sulfide solid electrolytes have garnered attention due to their properties that make them ideal candidates for industrial-scale battery production. Their research seeks to uncover efficient methodologies to develop these materials, ensuring both quality and cost-effectiveness.
In addition to research, the companies have outlined plans for a large pilot plant. This plant’s aim will be to rigorously test and refine the materials, ensuring they meet the demands and standards of mass production. This collaboration signals Toyota’s ambition to catch up with competitors in the electric vehicle market. Their commitment, especially in partnerships like these, underscores the company’s drive to expand its battery EV lineup, positioning itself as a significant player in the rapidly evolving EV landscape.
