Toyota Planning EV Battery With Four Times More Power
The batteries in electric vehicles are one of the biggest reason for range anxiety, but new technology from Toyota could put those fears out of mind, providing three, four or even five times more power than current lithium ion batteries.
Toyota is targeting a launch in the year 2020 for solid state batteries in cars. Solid state batteries are considered more compact and more efficient, allowing a higher voltage to be packed into a smaller package thanks to the use of a solid electrolyte instead of the liquid one used in current lithium ion batteries. Compared to current lithium-ion batteries, they can deliver three to four times more power.
Furthermore, following the use of a solid-state battery, Toyota plans to release a lithium air battery, which will prove to be even more powerful than solid-state batteries. Lithium air batteries are lighter and more energy dense, due to the replacement of current lithium cathodes, with ones that interact with oxygen. They are expected to offer a five-fold improvement in power compared to the current lithium-ion units.
Both kinds of batteries are seen as the future of EVs thanks to the weight savings, and lower internal resistance, making for quicker charges. With a power density that is just 1/50th of gasoline, current lithium ion powered EVs are having a hard time in the market, and are a niche product.
With these new solid state batteries and lithium air batteries, the power density will be much closer to what is offered by gasoline.

To me, the biggest of the biggest problems with EV is the recharging time. It doesn't matter what new batteries they're coming out with, the higher capacity the batteries has the longer it'll take for them to be recharged because there's only so much current you can draw from even the best quick charging stations. If it takes more than 10 minutes to recharge it'll not be able to replace gasoline vehicles. Not everyone has that much time to waste at recharging stations.
The only way to make EV acceptable as a replacement for ICE vehicles for me is to make all the automakers agree on a common packaging for some kind of solid-state battery so that it's easily swappable with the fully recharged ones at the "recharging" stations (but they'll have to be manned, adding to the costs, unfortunately) so that the battery swapping can be done in 5 minutes, but that'll almost certainly screw up the weight distribution because the batteries will then have to be placed at an easily accessible part of the vehicle, which is never going to be the bottom center of the car.

I think that in the future, PHEVs have much better chances than EVs for getting a lot of sales... I see people getting 20-30 mile PHEVs that can be charged in minutes with these new batteries and via some wireless system as soon as you park somewhere. They can also give you extra 100hp bump if needed for extra power.
Due to their nature, EVs are simply not efficient at fast speeds and long trips.

Just put this new battery in the next Lexus hybrids and I'll be satisfied.
Imagine : all the advantages of hybrid ( instant and seamless torque, fuel efficiency) with minimal weight penalty.
The mind boggles.

Regarding the press release its nice to see Toyota developing "even more advanced" batteries but what ever happened to Panasonic joint venture lithium batteries development that we had a chance to read about every month or so almost ten years ago? I guess one big nada.

Recharging stations are not the way to go. Charging the car while driving is the future but it will take government effort to implement such a technologies in the road infrastructure.

It is by far biggest car battery producer in the world, making 1.6 million packs last year where competition did 20-30k max.
Toyota started their battery research as far as 2006 and accelerated it in 2010 where they have program with 4 major universities in Japan as well as their own labs, coperating to create next generation battery.

The tech is moving fast..... they really help with city MPG.... I really wish the GS 450h was offered here in F-sport trim
Just waiting for the anti-greenie to post.......oh wait it happened already

Totally agreed. The best thing about the battery advancements in realistic terms is that it'll enable the next-gen hybrids to perform better and be more efficient while sacrificing even less cargo space. Hopefully Toyota will see the same and put these batteries in their hybrids instead of just EVs.
