Toyota has announced plans to launch the world's first electric vehicle equipped with all-solid-state batteries in 2027. The project is making progress thanks to a new agreement with Sumitomo Metal Mining Co., Ltd., which will handle the mass production of cathode materials.
The two companies have been researching this technology since 2021, focusing on resolving key challenges in creating stable and durable solid-state batteries. Sumitomo used its own powder synthesis technology, which enabled Toyota to develop a durable cathode material.
Solid-state batteries differ from traditional batteries in that they use a solid electrolyte rather than a liquid one. Toyota has received permission from Japan's Ministry of Energy and Transport (METI) to produce these batteries in Japan.
The automaker is also partnering with oil company Idemitsu Kosan Co., Ltd., which is building a lithium sulfide plant, a key material for these batteries. This new initiative is part of Japan's ambitious plan to build an independent battery supply chain and reduce its reliance on China and South Korea. Toyota has invested over $7 billion in this area.
