Toyota to launch world’s first practical all-solid-state EV battery

Toyota Motor Corporation has announced a significant breakthrough in developing all-solid-state batteries for electric vehicles (EVs), partnering with Sumitomo Metal Mining to mass produce cathode materials essential for these next-generation batteries. Targeting a launch as early as 2027, Toyota aims to introduce the world’s first practical all-solid-state battery-powered EV. These batteries replace the flammable liquid electrolyte found in traditional lithium-ion cells with a solid one, promising improvements in energy density, safety, lifespan, driving range, charging speed, and output. Toyota highlights that their new batteries will be smaller, more powerful, longer-lasting, and less prone to overheating, potentially transforming the global EV market. Since 2021, Toyota and Sumitomo have collaborated to overcome challenges like cathode degradation, using Sumitomo’s proprietary powder synthesis technology to develop highly durable cathode materials. Sumitomo plans to begin mass production of these materials by Japan’s 2028 fiscal year, aligning with Japan’s broader strategy to build
