Toyota reveals next gen battery EVs with 621-mile range from just 10 minutes of charging

"We are aiming for a 20% increase in cruising range, a 40% reduction in cost, and quick recharging in 30 minutes or less (SOC=10-80%) compared to the current bZ4X and considering installing it in BEVs in the popular price range," said a statement from the firm.

In parallel, Toyota will also develop a high-performance battery that combines a bipolar structure with a high nickel cathode to achieve further advances, which will be put to practical use in 2027-2028. According to the firm, it will achieve even "greater performance than the performance version of the square battery, with a 10% increase in cruising range, a 10% reduction in cost, and a quick charge time of 20 minutes or less (SOC=10-80%)."

Solid-state batteries

The Japanese carmaker plans to explore options to introduce solid-state cells for BEVs. Such batteries use solid electrodes and a solid electrolyte instead of the liquid or polymer gel electrolytes found in lithium-ion or lithium polymer batteries. Such batteries are found to be more durable with an increased lifespan.

Toyota is developing a method for mass production of such batteries, striving for commercialization in 2027-2028. "We are looking at a 20% improvement in the cruising range compared to the performance version of the square battery, while costs are under scrutiny, aiming for a quick charge time of 10 minutes or less (SOC=10-80%)." A higher-level specification is also being researched and developed concurrently with an eye toward the future.

The firm is also looking at expanding its presence in the fuel cell market by promoting external sales of fuel cells using Mirai's hydrogen units, with the firm already receiving offers for external sales of 100,000 units by 2030. They will also set up a body called Hydrogen Factory in July, which will be "able to make immediate decisions under one leader, from sales to development and production, all at once."
