Toyota's 745-mile Battery

"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."
 
I'm not jumping on the EV band wagon until I can get a 1,000 miles of range. (more than the vast majority of what bladders will do on here before a bathroom stop is needed).
You know...that goal post keeps moving when the objections are solved.....

Even if the range is reduced to half of 745 miles in the winter...........

You jest, but I hear this daily. They just aren't as practical as driving out of route to buy expensive gasoline once a week, paying for maintenance and idling in traffic.

You won't believe this, but if you use electricity in the car, it...uses electricity from the battery!
 
Solid State batteries are 1/3 smaller. The lithium they contain has the same number of ions as any other lithium battery. The smaller size comes from eliminating the carbon anode. The idea that they are 2x more energy dense is incorrect.

Due to the "solid" nature of the components, getting sufficient ions to move (internal high resistance) often requires elevated temperatures.

Absurd range claims are in fact possible, with huge batteries. The SS battery only somewhat changes the equation from today's best cylindrical cells. Tesla can do the same "trick" now by making the car's battery 200KWh instead of 100KWh.

SUMMARY
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.

Secretly developing? This has not been a secret, ever.
Everyone in the industry knows that Toyota has joined with Panasonic to develop solid state batteries. It will be the next big leap in battery technology once they get the format fully developed and they have a solid handle on manufacturing costs. The Toyota/Panasonic effort is not the only one happening. There are several other companies that are well along in their R&D of solid state batteries. It is a race to the finish line and I am personally excited by the technology, it is truly game changing technology.
 
Phase 1, find quality materials (per the article)

Phase 3, profit.

This has previously been discussed in this thread:
https://bobistheoilguy.com/forums/threads/toyota-bev-announcement.370024/page-8#post-6524429

(linked to my comments on the matter).
 
The engineers at Tesla's Advanced Battery Development Division have done some experimental work with solid state batteries as well. As stated above, what Toyota has been doing is no secret and other companies would like to go with solid state batteries if and when the problems could be worked out.

But for the foreseeable future the current cell architecture that Tesla is using will continue to be refined with emphasis on reducing costs, improving manufacturing techniques and production speed & volume and increasing power density. And I have no doubt if Toyota or anyone else solves the problems with solid state batteries that Tesla and others will adopt them the very next model year.
 
I'm a Toyota guy and I don't hate EVs but I'm still going to say let's wait and see. Now if it does get around 650 miles real world then that would be great.

If you are referring to Le Mans, Toyota taught both of them a lesson from 2018 through 2022, placing 1st and 2nd in 4 of the 5 years.
IMO Toyota would have won again in 2023 if it hadn't been penalized by Le Mans adding additional weight to the dominant Toyota GR010s in a controversial “balance of performance” adjustment designed to level the playing field (Toyota still came in 2nd). They did the same thing to Ferrari's 333SP in the 1990s causing Ferrari to withdraw from top level sports car competition.

So if they're more expensive, this means the battery is going to increase the cost of the vehicle, over 3X what it does in an otherwise equivalent, 248 mi. range vehicle using a conventional battery?

I'd rather have a hundreds of pounds lighter weight, 248 mi range vehicle using a smaller solid state battery. Imagine if with 1/3rd the capacity, it could charge in 3.3 minutes instead of 10. This also means a charging station can charge more vehicles per day, especially during peak demand. I know that charging time wouldn't be reduced that much because you can dump more current into a higher capacity battery of same construction and voltage but a lower capacity equivalent battery should still charge faster due to the lower capacity because of other practical limits.

Porsche didn’t race 2018-2022. The fact remains anytime Toyota has any real competition, they fold.
