PC Mag - "No More EV Battery Replacements? VW's Solid State Cell Holds Up for 300K Miles"

"Volkswagen did not create the new battery; it was developed by QuantumScape, a California-based battery technology company. QuantumScape provided a prototype to Volkswagen Group-owned PowerCo, which then tested its performance over several months.

The results far exceeded expectations. PowerCo says the cell retained 95% of its range capacity after 1,000 charging cycles, or the equivalent of roughly 300,000 miles. The current industry standard for EVs targets 20% capacity loss over 700 charging cycles, which means an EV that starts out with a 250-mile range could end its life with a 200-mile range. But with the QuantumScape solid-state battery, it would theoretically only go down to approximately 240 miles of range after much more driving."

A Volkswagen would be nothing more than a battery and axles by 300k miles.

Are you sure about the axles?!

Good news, QS stock jumped almost 50% today. This means I'm only down 90% from when I bought it!

If you put the broken ones in the trunk

If they can make commercially viable solid state batteries, it will be the holy grail of EVs. Faster charging, higher energy density, lighter, more cycles, no risk of fire etc. This is what EV industry needs to put ICE to grave yard. Cant come soon enough.

It's good but ironic that VW (emissions scandal) is the one doing this. It would be nice if something like this comes along and we can replace our batteries.

Even better to see an American company doing this.

They're just a large investor in QS, among others (and QS being public).

What trunk ?

Toyota says they will produce EVs with solid state batteries by 2027-28. Exciting time to be alive..

Toyota has been announcing solid state batteries for more than 10 years now. They are always "just around the corner".

In order to produce EVs with solid state batteries, Toyota will first need to be able to produce EVs. That's not happening either ...

This is an excellent example of a straw man argument. And it's probably the one that irks me the most when someone tries to argue against EVs.

How many people do you know that have replaced their batteries out of warranty and thrown the old one in a landfill? Zero? That's what I thought. But EV owners do need to be aware that degredation is a thing and if they are using traditional lithium ion, be prepared to accept it or not. And by not, I mean lease it or don't buy it.

Also, it's worth mentioning I'm on my original 90kwh pack with 200k miles and I'm sitting at a solid ~26% degredation.

The thing that pisses me off about that is these people act like ICE vehicles are trouble free and as good as the day they were bought throughout their lifespan when mileage and power goes down in engines as usage goes up.

An ICE car with 200k miles on it has a really tired engine and I've seen some of these EVs have their drive motors looking brand new still after 200k. EVs wear better than ICE no question.

Hopefully the promising research being done with solid state comes to fruition by the end of the decade.

I've followed QS over the years and have heard about breakthroughs before, but if they are compounding then we should be getting somewhere incredible.

One of the biggest problems with solid state is that once we finalize a viable product (testing testing testing), it's going to be 5 years before the production infrastructure can build then at scale. End of the decade would be amazing.
