For over a decade, Toyota has taken a reserved approach to electric vehicles, offering just one fully electric model, the bZ4X SUV. But now, the company is moving aggressively to catch up, announcing that it aims to launch its first mass-produced EVs using solid-state batteries as early as 2027. The technology behind these batteries, developed in partnership with Japanese petroleum company Idemitsu Kosan, marks a major leap forward in range, charging speed, and durability.
According to Toyota, the new batteries will offer a driving range of up to 745 miles far exceeding current industry standards. For context, the Ford Mustang Mach-E, the current record-holder, managed 570 miles on a single charge during a UK-based test. More impressive still is the charging time. Toyota claims its solid-state battery can fully recharge in under 10 minutes, addressing one of the biggest barriers to EV adoption: convenience. This charging speed would rival that of refueling a gasoline vehicle, significantly reducing downtime for drivers.
Durability is another area where solid-state batteries shine. Unlike conventional lithium-ion batteries, which typically last for around 1,500 to 2,000 charge cycles, solid-state versions can reportedly endure between 8,000 and 10,000 cycles. Harvard researchers have suggested these batteries could even last for up to 30 years, far outpacing current expectations for EV battery longevity. This kind of lifespan not only reduces the need for replacement but also makes electric vehicles a more sustainable and economically viable option in the long term.
What makes solid-state batteries so different is their use of solid electrolytes instead of the liquid ones found in lithium-ion systems. This change enhances safety by reducing the risk of leaks or fires and allows for greater energy density, meaning more power in a smaller, lighter package. The result is an EV battery that’s safer, charges faster, lasts longer, and takes drivers farther.
