Wall Street Journal reports that Toyota nears technological breakthrough in electric-car batteries, working on a new type of battery that could hold a higher charge and uses a solid electrolyte instead of the commonly used semi-liquid version of today's lithium-ion batteries. Toyota hopes to put the new batteries in its electric cars as early as 2020 and nears a breakthrough.
The latest rumor is that Toyota will have long range solid state batteries by about 2020 that will completely change the market. We will have to see about that. But I think it certainly is possible.
Toyota was acting like it was staying out of battery and going all hydrogen and I remember thinking that seemed odd as you wouldn't see major electric cars coming out of Toyota or at least planned by Toyota at a level of Nissan Leaf or Tesla Model S or Model 3. Toyota developers were apparently playing chess with the other automakers, most notably Nissan and Tesla.
If this all becomes reality and they use standard plug this could really be a huge breakthrough from Toyota.
On the other hand, as I mentioned in the opening paragraph of this story there is an open question. If all goes well Toyota's new solid electrolyte batteries will be available in 2020, and what will all the other battery manufacturers have in 2020? The playing field doesn't stand still, and while Toyota is sitting on its tech, others have it out in the real world doing heaps of testing.
In any case, just like there are many car companies to choose from, EV will be no difference.
