I'd be happy to buy a big, bulky, heavy, early version of any of these batteries for my house, as long as it's affordable, high capacity, and has a good cycle life.

It doesn't even have to fit in a car, it can be the size of a shed. Hell, I'll build a shed for it.

Yet this magical product has yet to materialize!

It's not vaporware, it's anti-EV FUD.

Don't buy one of those EVs, we're going to have much better EVs really soon now and you'll be stuck with something inferior. Same with their talk about hydrogen: EVs are just a fad, hydrogen is the future! ... and it'll be viable real soon now, so stick with gasoline until then!

Toyota is constantly in the news about battery advancements or hydrogen because it's defensive FUD to protect their fossil fuel vehicle sales.

The size of the company making the claim has no correlation to the veracity of the claim.

BP, Exxon, Shell spent decades claiming global warming wasn't real.

Philip Morris & British American Tobacco spent decades telling us smoking didnt cause cancer.

All of whom are or were as large as Toyota.

Look at their track record and judge their words against their actions.

Toyota has spent considerable sums over many years campaigning against Electric Vehicles.

So should you believe a company that says it's about to table the next huge EV breakthrough when it fouht tooth and nail to slow that transition ?

Your choice, but I won't until I see something more substantial than press releases

I don't think it's vaporware, but they keep pushing the timeline. Years ago there was advancements and we were going to see it in 2026. Now it's 2027/28. In 26 it'll be 29/30

They'll get there eventually, the tech is real, it's just super new tech at scale is hard.

I don't think time affects a companies ability to reinvent physics. At the end of the day you are limited by the laws of nature

I doubt they're using pressure to prevent the dendrites. Honda figured out a while back to separate the parts in some sort of polyplastic mix of some sort in order to prevent the formation. I bet toyota is also going more that route.

Imagine putting your tongue on the charging plug

Spread it over enough people and it's the same energy. For one person it's a much shorter charge. Over a population with random charging times it's the same consumption off the grid. The problem then becomes a distribution issue, not a production issue.

Likely these kind of chargers will be expensive and at supercharge stations. Homes will use lower over longer.periods as it's rare you want to pop home for 10 minutes needing a full charge.

This is a big step forward, no matter how you look at it.

It might be also useful for excess storage when we have wind and solar energy that the grid doesnt need. Being able to do so rapidly will mean a smaller array of batteries required for grod storage.

Assuming efficiency of ~4 miles per kWh (on the high end of current EV efficiency)

Why should we assume this?

I'm not sure people are going to be interested in paying for megawatt-capable chargers, anyway. There's a couple of sites near me that have old 50 kW chargers and new 250 kW chargers, and have higher prices on the 250s. I expect that sort of thing to continue - providers are going to want to cover their costs and higher powered chargers are more expensive to buy and operate.

I'm getting close to 8m/kwh on the high-end. Realistically, I'm ranging between 3.6 to 5 m/kwh. But when I drove for Uber, I did 200 miles using only 34.1 kwh, I drove slow, and it was mostly city driving. So I could only need 137 kwh for 800 miles. Still prohibitively unrealistic to charge in 10 minutes. It's about 1.4 MWatts to charge from empty for 10 minutes.

the charge power needed for the 200KWH is not 1.2 MWatts for 10 minutes, it's 2MWatts. Mostly because you can only charge fast at lower percentage.

That would be impractical even for fleet vehicles.

Unless they're also going to announce the development of nuclear fusion in order to provide the necessary cheap energy, then I don't think this is going anywhere.

Look at Toyota's lobbying history. It's a load. They push the hardest against EV mandates.

I, too, eagerly await the release of phones with a 1200km range.

People keep saying that but they've been using batteries to make wheels spin longer than any major manufacturers. The Prius came out in 1997!

you could understand it as: the technology has the capacity to receive power that fast without breaking or catching fire

They don't need to be big.
