Toyota confirmed this week that it’s developing a solid-state battery to be used in vehicle electrification. Compared to conventional lithium-ion, solid-state lithium-metal batteries are much lighter, more powerful, take up less space, charge faster, last longer and present much lower risks for flammability.

While Toyota, the parent company of truck manufacturer Hino, won’t reveal much on the matter, they did offer the following statement:

Next-generation batteries, such as solid state and metal-air batteries, are safer and demonstrate higher performance than lithium-ion batteries. We are currently working on the research and development, including the production technology of solid-state batteries, and we have achieved ultra-small BEV driving. We are accelerating development aiming for commercialization by the first half of the 2020s.

No word yet on whether Toyota’s commercial vehicle affiliate Hino will be using the company’s solid-state batteries. Hino has used conventional lithium-ion batteries in its hybrid trucks.

The Nikkei, which bills itself as a the world’s largest financial newspaper, called Toyota’s solid-state battery ‘game changing’ and added that the automaker is aiming to become the first OEM to market an EV powered by the technology. The paper added that the first prototype will roll out this year and arrive at dealers sometime in the early 2020s.
