Toyota wants to commercialize solid-state EV batteries by 2022, reports say
According to reports in The Wall Street Journal and Japan’s Chunichi Shimbun, Toyota is in the “production engineering” stage of building an electric vehicle (EV) battery with a solid electrolyte. Reports suggest the new battery will debut in Japan in a model 2022 car with an all-new platform.
So-called “solid state” batteries have both solid electrodes and solid electrolytes. Solid-state batteries can be made smaller and lighter than the lithium-ion batteries that currently power electric vehicles, but engineering such a battery at an attractive price point for mass production has been a challenge. The Chunichi Shimbun reported that Toyota’s battery will be able to charge in a few minutes and have a long range, but the article did not list specifics.
A solid-state battery would also reduce the fire risk that comes with lithium-ion batteries that use a liquid electrolyte. And, because the electrolyte wouldn’t be in danger of freezing, it could withstand a wider range of temperatures.
