An electric solid state battery? Toyota could be working on it facing 2022

Toyota's hybrid tradition goes back to the original Toyota Prius in 1997, and although the Japanese giant has no idea of ​​abandoning this strategy for its vehicles, it explores new possibilities such as hydrogen (already puts it to the test In a truck) or pure electric. In fact, the Japanese press is already talking about a future electric vehicle for 2022.

That Toyota prepares the launch of a 100 percent electric car is not the news of the century, but the technology that will use the model. While the entire industry is turning to liquid-electrolyte lithium-ion batteries, Toyota would be working on solid-state batteries, ie with solid electrolytes instead of liquids, with the benefits that this entails.

It is the Japanese newspaper Chunichi Shimbun who ventures to announce this electric by 2022 with innovative technology. It would use its own platform and would have an autonomy superior to the competition. At the moment Toyota has not confirmed or denied the rumors, although last year already dropped that an electric vehicle finally entered its plans.
What is a solid state battery?

This solid state battery technology is, according to experts, a couple of years from the market. Manufacturers like Samsung or LG have been working on it for some time (Hyundai, among other brands, is also investigating in this direction), and best of all is that when they become reality could change the market for batteries forever.

In essence, solid state batteries are devices whose energy storage cells are not filled with a conductive liquid like the batteries we all know. Instead they use a solid compound (lithium metal in this case, although magnesium or sodium could be used, for example) which does the same function as the liquid electrolyte, ie transmit the ions between positive and negative poles.

It has many advantages?

If you are wondering what is special about this step from liquid to solid electrolytes, we will tell you that the advantages are many and varied. From capacity or recharge times to safety, although that yes, would be something bigger and heavier.
Thanks to the use of a solid compound for the cells, this type of batteries have a higher energy density, so they have more capacity (it is said that double would be feasible). In addition, the recharging times of the battery itself, which for current lithium-ion batteries are at least 20-30 minutes at rapid charge, could be reduced to six times less, ie only a few minutes.

Solid-state batteries, on the other hand, are much less hot than liquid ones, so safety is also improved, much less the risk of fire or even explosion in case of impact. Moreover, the useful life promised by these batteries could be up to five times higher than the current ones and the passive drainage (discharge of the battery when not using it) is greatly reduced. The technology promises, of course.
