Toyota Aims to Launch the 'World's First' All-Solid-State EV Batteries

Toyota is fast-tracking its long-promised all-solid-state EV batteries through a new partnership with Sumitomo Metal Mining, aiming to debut its first production vehicle using the technology by 2027 or 2028. Electrek reports: Toyota said that its new batteries could significantly enhance driving range, charging times, and output, potentially transforming the future of automobiles. Compared to current liquid-based batteries, which use electrolyte solutions, Toyota's all-solid-state batteries utilize a cathode, an anode, and a solid electrolyte. According to Toyota, the next-gen battery tech "offers the potential for smaller size, higher output, and longer life." The two companies have been developing cathode materials for all-solid-state EV batteries since 2021, focusing on some of the biggest challenges in producing them at a mass scale. Using Sumitomo Metal Mining's proprietary powder synthesis technology, Toyota claimed to have developed a "highly durable cathode material" for all-solid-state batteries. Sumitomo has been supplying cathode materials for electric vehicles for years, but it's now working to introduce the newly developed tech, moving it toward mass production.
