Toyota Secures Approval for All-Solid-State EV Battery Production in Japan, Aims for 2028 Release

Japan’s Ministry of Trade and Industry has granted Toyota approval to develop all-solid-state electric vehicle batteries. This certification enables Toyota to lead the next generation of EV battery production in Japan, with plans to release high-performance batteries offering a 620-mile range by 2028.

Toyota Gains Approval to Develop All-Solid-State EV Batteries, Aiming for Mass Production

Japan's Ministry of Trade and Industry (METI) officially approved Toyota's designs for all-solid-state electric vehicle batteries. The certification authorizes Toyota to construct and develop the next generation of electric vehicle batteries as part of Japan's initiatives to increase domestic supply.

Toyota has disclosed that numerous subsidiaries have been granted METI certification to manufacture electric vehicle batteries.

Due to the certification, Toyota is authorized to manufacture next-generation batteries at Prime Planet Energy Solution and Primeearth EV Energy. It also received approval to construct all-solid-state electric vehicle batteries.

Toyota-affiliated companies are gradually transitioning to all-electric models but continue mass-producing batteries for their hybrid models, per Electrek.

Toyota acquired complete ownership of Primeearth EV Energy, a joint venture with Panasonic, earlier this year. Toyota asserts that the action allows it to "respond flexibly to the increasing demand for batteries."

The Japanese auto giant intends to collaborate with its subsidiaries while transitioning to mass production of "a wide range" of EV batteries.

Last year, Toyota disclosed its roadmap for electric vehicle batteries, encompassing numerous varieties. The initial "Performance" batteries are scheduled for release in 2026, with the "Popularization" batteries following the conclusion of 2027.

The former is anticipated to offer a WLTP driving range of nearly 500 miles (800 km), whereas the latter is expected to achieve a driving range of approximately 373 miles (600 km). Both will offer substantial cost reductions compared to the current bZ4X electric SUV.

Toyota Plans 2028 Launch for High-Performance EV Batteries with 620-Mile Range and 10-Minute Charging

Toyota anticipates introducing its "High Performance" batteries in 2028. These batteries will offer a WLTP driving range exceeding 620 miles (1,000 km) and rapid charging in 20 minutes.

Toyota also asserted that it had discovered a "technological breakthrough" in the form of all-solid-state electric vehicle batteries. Around 2028, the company anticipates the release of its initial solid-state batteries, which will feature a WLTP range of more than 620 miles (1,000 km) and a 10-minute rapid charging period.

The company will manufacture the Performance Version of the next-generation EV batteries in 2026, and the transition will be implemented incrementally. Toyota's objective is to achieve an annual production of 9 GWh; however, an established timeline has yet to be established.

Several Japanese corporations, including Toyota, are investing $7 billion (1 trillion yen) in increasing domestic battery production.

Japan's objective is to establish a consistent supply of batteries as it transitions from its dependence on China or South Korea, which currently dominates the market.
