Toyota promises long-range solid-state batteries in EVs by early 2020s

REPORT: AUTO GIANT BETTING ON ADVANCES IN SOLID-STATE BATTERY MANUFACTURE
JULY 25, 2017


Toyota has only recently expressed interest in pure electrics, as opposed to plug-in hybrids, but a new report says the auto giant is planning to leapfrog early electric car leaders by debuting an EV with all-solid-state batteries by 2022. The Japanese daily Chunichi Shimbun (via Reuters) reports that Toyota is focusing on this technology, distinct from lithium-ion batteries, in an effort to market a car with a significantly longer range and a shorter recharge time.

Current EVs use "liquid" lithium-ion batteries, but Toyota, along with a number of startups and suppliers such as Bosch, has been investing in solid-state battery tech that replaces liquid acid electrolytes with solid materials that are less prone to short-circuiting, catching fire or degrading over time, among other desirable properties. The lack of acids in such batteries is expected to bring their manufacturing costs down considerably once the technology is ramped up to production levels, also eliminating the need for the environmentally unfriendly manufacture of lithium-ion batteries. Solid-state batteries also hold the promise of offering roughly twice the energy density of lithium-ion and other "liquid" batteries per pound, which makes their use in EVs attractive once the technology is perfected and commercialized.
