Toyota Planning Long-range EV Using Solid-state Batteries by 2022

Toyota, the company that came out with the Prius in the 1990s and decided it had perfected the electric car, may be looking regain its EV advantage by 2022. It’s not something you’d expect to hear, considering Japan’s largest automaker has lagged behind in terms of competitive electric development for the last few years.

While its hybrid program got the drop on the competition, it subsequently favored hydrogen fuel cells over purely electric vehicles as the next automotive epoch — creating a bit of an industrial dinosaur.

Fortunately, Toyota has no shortage of muscles to flex. Once news broke that Toyota was earnestly considering electric R&D, everyone speculated it would be competitive at roughly the same time as other automakers. Not so. On Tuesday, Japanese newspaper Chunichi Shimbun reported Toyota has quietly upped its game to surpass them.

Earlier this year, Toyota filed a patent for solid-state lithium battery technology. While that isn’t noteworthy in itself, as numerous automakers have done the same, Reuters cited Chunichi Shimbun as claiming Toyota is working on bringing the technology to a long-range electric car in 2022 — several years earlier than most companies’ best estimates.

The advantages of solid-state batteries are numerous. It’s assumed they possess an energy density ideal for BEVs, likely offering greater range than what’s currently available. They also pose almost no fire risk, provide a longer lifespan, and can charge extremely quickly. While the Japanese report did not reference its sources, it alleged Toyota’s phantom model would achieve a complete charge “within minutes.”

Toyota’s new electric car is would be built on an entirely new platform for Japanese production in 2022 — which is, interestingly enough, right around the time the next Prius will be due.

Assuming Toyota comes out with a solid-state BEV before its rivals, it would have a huge advantage on the market. However, cost is unlikely to be among them. At present, the batteries are extremely expensive to produce. Toyota would not only have to hone the technology for cars but also find a way to construct, or source, the units without going bankrupt.

“There’s a pretty long distance between the lab bench and manufacturing,” said CLSA analyst Christopher Richter. “2022 is ages away, and a lot can change in the meantime.”

Toyota spokeswoman Kayo Doi told Reuters the automaker was unwilling to comment on specific product plans but added that it aimed to commercialize solid-state batteries by the early 2020s.

    "2022 is ages away" It's one vehicle model cycle from now, Mr. Richter. It's incredibly soon, and unless someone has something better in the pipeline, it will not be released by 2022. Anyway, the real gem of this technology is rapid charge because charge time is the real cause of range anxiety, not limited range. If a car could be recharged in 60 seconds, few people would care if it only had a 100mile range. However, charge times are also affected by the recharging infrastructure. I do not foresee rapid charging stations on every street corner by 2022 so this will affect Toyota's plans, regardless of how good solid state technology is.

      It's a Toyota. They won't have much trouble bundling hybrid functionality. Slowly, if at all, phasing it out as batteries and infrastructures become more available and cost effective.

C'mon, TTAC, lets have some balanced journalism here. It's your job. =======================
