The automotive industry is set for yet another big leap next year, as Toyota is reportedly on the verge of rolling out its game-changing" solid-state battery. The Japanese carmaker plans to be the first to sell solid-state battery-powered EVs this decade, and that it will be unveiling a prototype in 2021. Toyota promises that the new battery will "be a game-changer not just for electric vehicles, but for an entire industry." Solid-state batteries are expected to become a viable alternative to the usual lithium-ion units that we see in most electric vehicles today. These new power packs offer greater energy density as well as lower risks of fire. Toyota claims that its newly developed batteries can also enable a maximum EV range of 500km in one full charge and a zero to 100% charging time of just 10 minutes, "all with minimal safety concerns." The carmaker adds that with these new batteries, its EVs will boast a maximum range that's double of what it would have been able to achieve with a traditional lithium-ion battery"and this is achieved without legroom being compromised to accommodate a larger battery pack. Toyota has yet to specify when exactly we'll be seeing the new battery ... in action. Other automotive manufacturers that are looking to use solid-state battery technology include Nissan and Volkswagen.
