Solid State Batteries

[dewaltdisney]

Does any egghead know if this is true or not? I read that a US company Qauntamscape and Toyota are both on the way to producing a new type of battery for EV's. They apparently will give ranges like 700 miles, recharge quickly (20 mins), are smaller and lighter, and do not have recharge degradation like Li-Ion. It all sounds too good to be true, any one know if this is really happening?

Solid state batteries have been available for a while, however they are still in their infancy.

Do you think it is the future for batteries? I would like one in my mini chainsaw.

Probably, but they have to get them to be reliable first. (oh and cheap) After market ones for any tool will be many years away.

Probably won't be available in our lifetime. The Government say they want to save the planet and be green but they'd lose too much in oil tax revenue. Apparently it takes 7 years after you buy an eco vehicle to draw level had you bought a fossil fuel vehicle. That's why they're so expensive.

Its all about money and control

Not sure I agree with that.

It seems to be more a case of:

You buy an EV. You loose. It is too expensive to...............do anything with them. New batteries cost more than the car, new parts cost almost as much as the car, add labour to fit part, car is a financial write off. There are no "after market" parts as there is no demand for them. Those that bought EV's a few years ago (Company fleets) are not buying them again as they are too expensive to run/repair or sell as 2nd hand. (Like they do with ICE vehicles)

That is right, current EV's suffer terrible depreciation as no one wants to buy them second hand. The advent of these alternate batteries could be a change for all that if they can get them right. Apparently VW has a 10 percent share in Qauntumscape and other manufacturers are also involved. Reading more it is unlikely that the batteries will become mainstream until 2028 plus with other manufacturers looking at hydrogen. Hybrids look like the compromise for the intervening period. We shall see.

@SE This is interesting https://www.youtube.com/watch?v=I1XmKpRFZco I would be interested in your opinion if you care to watch it.

I watched half of it. The video is not from the battery company, its some blokes opinion on what the battery company are/claim to be doing. Give it more time.

By second hand I assume you mean a vehicle that has been driven for a few years. To be pedantic a large number of EVs are being sold as second hand though . Manufacturers are mandated to sell 22% of the cars as EV’s and in the UK they reached a level of 23% . However , it seems that there is basically a scam going on whereby cars are registered as pre sold and subsequently sold as second hand with discounts of up to 30% on the new price.
As to hydrogen the idea of millions of private cars powered by it is little more than a petrolhead’s wet dream. The economics and energy returns are completely against it , it makes no sense at all except for certain specialist vehicles.
But for balance I don’t think EV’s are an answer , I don’t feel there is an actual answer to those who want BAU . The real answer is a societal change .

I used to trade in cars for a while when I retired and I still meet occasionally with guys who are still trading. They have said that no one in the trade will touch an EV as they are a nightmare to sell. The degradation of the battery over so many charging cycles sees the range diminish. I learned this is due to dendrite, a chemical tree like structure that grows in the battery. This reduces the charge capability and in certain cases the growths can breach the separator causing a short that can lead to a fire. Add to this the potential of £20k to replace a failed battery and you can see why they are out. An ICE power car will usually depreciate 50% over three years and a lot of this will have been the original VAT paid. There is a well documented case on YT where an electric Porche Taycan which was £120,000 new reduced to £32k in three years, nearly 75% of value lost. There are fields full of unsold EV's, no one is buying. The advent of solid state batteries gives hope through quick charging, double the range, and cheaper to produce. But they are still working to solve the dendrite problem. I am watching with interest. This is worth a look on the Autoalex channel https://www.youtube.com/watch?v=x16JEo94wQQ A

They’re going to have to sort something out soon, it’s been put back to 2035 but by then car manufacturers will have to be 100% EV .

It was a guy at work who is responsible for some Fleet vehicles that told me. Granted this was about 10 years ago.

For those of you following this thread, this explains dendrites https://inside.lgensol.com/en/2023/07/b ... dendrites/ It gives you an idea why the charge diminishes with recharge cycles and explains lithium battery fires (news suppressed for EVs)
