Toyota confirms solid-state EV batteries for 2027–2028, targeting 1,000 km range and 40-year durability

Toyota has confirmed that its solid-state battery program is on schedule and says it intends to be among the first automakers to bring the technology to market. By the company’s estimate, production EVs with these batteries could appear as early as 2027–2028. The timeline sounds ambitious yet within reach.

The headline promise is durability that borders on the extraordinary. According to Keiji Kaita, who leads Toyota’s battery development, engineers are already pursuing a lifespan of up to 40 years. In practice, that would allow a car to serve several generations of owners while spreading manufacturing impact over decades and significantly shrinking its carbon footprint.

Solid-state cells offer more than longevity. Targets include up to 1,000 kilometers on a single charge, higher energy density, lower weight, more compact packaging, and production costs that are more accessible than conventional lithium-ion chemistry. If these goals are met, the technology could reset expectations for what an electric car can do between charges.

Durability is not a new theme for Toyota. The brand’s current hybrid batteries come with a 10-year or one-million-kilometer warranty. Now the company aims to carry that mindset into the EV era, developing packs designed not only to last, but to be straightforward to replace even after decades. In real-world ownership, that focus on serviceability could prove as valuable as raw range.
