  • Toyota has been secretly developing a solid-state battery for EVs with a range of 745 miles and a charge time of 10 minutes, which could revolutionize the industry.
  • The battery will provide EVs with the same driving range as traditional vehicles, eliminating the need for frequent charging stops during long trips.
  • While Toyota has been a proponent of hydrogen cars, this breakthrough in EV batteries suggests a shift in the company’s approach to the post-ICE future.

Perhaps we’ve gotten too accustomed to the tech-bro approach to corporate PR, in which companies loudly trumpet every half-baked idea that may or may not fizzle into anticlimactic failure. Today, a company waiting until a concept is totally finished and ready for deployment seems almost quaint. While Toyota has hitherto seemed staunchly opposed to EVs, its research and development department has been developing what may be the biggest breakthrough in EV batteries away from the prying eyes of publicists: a solid-state car battery with a range of 745 miles and a charge time of ten minutes. (For those who prefer metric, that’s a range of 1200 kilometers and a charge time of six hectoseconds.)

For the first time in the history of mass-production EVs, a battery-powered car will have the same driving range as one with an engine and a gas tank. Anyone listening carefully will hear EV-driving dads breathe a sigh of relief as they contemplate how they won’t need to pull over and pry their children away from convenience store candy shelves every two hours while they wait for the car to charge. The great family road trip hasn’t gotten any more bearable in the post-engine era, but may get a bit more cheapskate-friendly.

What Is A Solid-State Battery?

solid-state battery is quite simple to explain. It stores its electrical charge in a solid electrolyte (other types of batteries use a liquid or paste-like one). They’re commonly used in small devices like pacemakers, RFIDs, and other things that demand little electricity. Because they have a very high energy density compared to other battery types (that is, they can store more electricity than other batteries of the same size), solid-state batteries seem like a natural fit for electric cars. But they don’t do well in cold weather, tend to weaken quickly after repeatedly getting charged and drained, are particularly costly, and have other issues that prevent them from going into every laptop, smartphone, and car.

The rise of EVs has made battery research a lot more profitable than it was a mere ten years ago, and scientists have been working on overcoming the shortcomings of solid-state batteries. Toyota is the first company that has come out and said it may have solved the range and battery weight problems.

If this becomes a production reality it solves many issues including range, recharge time, battery weight & eliminates lithium.
