First Commercially Viable Solid State Battery From QuantumScape, Doubling Tesla's Wh-kg Ratio

QS ssb energy density 1kWh/L, four times the energy density of model 3 battery. This point alone proves that you really do not know what you are talking about.
All Tesla ev battery have at least 650 Wh/L energy density.

How much will it cost? When will the battery be ready for testing? There are quite a few questions, that must be answered, before the battery can be mass produced for a vehicle. How long before a vehicle is ready?

This is great news. Tesla batteries are plagued with rapid degradation, typically 10% the first year and it seems like weekly fires now. Hopefully these new batteries will be safe and longer lasting.

Good progress. With further development it could become just as good as Tesla' 4680, which is already in proven production.

I believe Tesla 2170 batteries had a energy density of 260 Wh/Kg

Only time will tell if it can out perform the industry standard li-ion battery packs. Cost, performance, life, and safety are the biggest issues facing all EV batteries. Will a solid state battery hold up in rough environment, like rough roads in the upper Midwest?

Now, this don't sound like the 12 million mile battery that is suppose to charge in 8 mins. Gos 9200 on one charge and last up to 12 million miles!! What company is producing that battery?? They are suppose to be out of California..

This will not happen anytime soon. When Tesla adopted the 18650 Li-Ion battery in 2009, it was already in mass production and had 25+ years of historical performance data. When QS has a prototype ready, it will have to be validated for many years in an automobile environment before it can be put in a mass produced auto. QS may make a car battery, but it will not be anytime soon. Meanwhile QS can survive on batteries for benign environments like portable electronics, power tools, stationary storage, etc..

While I think these developments are exciting and potentially game changing, the issue with solid state batteries isn't so much the ability to painstakingly make them in a lab, it's their mass producability. Or rather, the lack thereof. They're extremely difficult to manufacture at scale, whereas traditional lithium ion batteries are pretty easy to manufacture at this point. What all this means is that manufacturing them in large volumes and at prices that will allow the cars they're used in to be affordable, is going to be the real test. And it's a massive obstacle to overcome. I hope they pull it off, I really do, but solid state is likely further away than one would like to believe.

I'm still expecting the lithium ceramic batteries to make it into production, as the eliminate dendrite issue completely. And durability and safety is absolute.

Wow, so many butthurt Tesla defence warriors here. They don't want anybody to ever develop new technology because it means Musk made another dubious move (as with LiDAR and fuel cells).

This is great news for all EV fans (it's only bad news for Tesla fanboys). This is the fifth time I've seen a breakthrough in solid state batteries have it's forum derailed by extremely nervous Tesla fans assuring each other that nobody will beat Tesla any time soon.
The truth is that Tesla are losing their edge by the day. There are more and more longer range, faster, quicker charging EV's by the day.

China will dominate the market soon. The thing that made Chinese cars so poor were the engine and transmission which are completely negated by electric motors (which the Chinese excel at).

Actually, if range improves 80% to say 800km then 800 cycles are not 240k miles but 432k miles. Just saying.

This article is so great it is unbelievable. No source of information given, no references to scientificaly obtained data. To me it looks like someone paid the author to write a pean to drop the peasants on their knees and rush them to buy some QS stock. Someone is literally inflating the bubble.

So impressive, eh ? Yet in the real world VW are still keen to drag their solid-state feet until some vague launch-point before 2030. If the performance is already proven there can be no credible excuses to delay roll-out into the real world for so long. The Chinese certainly won't drag their feet VW-style. And S.Korea's leading battery-manufacturers won't want to be humiliated or left behind by China.
So what's the excuse/problem, VW, Quantumscape ? The usual "..very difficult to 'scale up' " ? "Difficult to move out of the lab unless cocked, loaded guns are held to your heads ?"

Hmm... Could one of those mysterious unnamed automakers testing QS battery be Tesla?

Sssh! Swiss company/startup set to start solid state production in..2023(!!). And its cobalt-free. Noone reading this will have read about it because all the usual, top-page-ranking EV sites have failed/refused to report it. Why ? Because 2023 is far too disruptively early for major carmakers outside China. Solid state stasis till 2028-2030 is the tacitly agreed schedule. Then solid state batts will be reserved for premium-priced EVs for 5-10 years.
So bring on the fast-track consensus-busters - whether from China, S.Korea...or Switzerland.
I'm not gonna give you the link to that Swiss startup - to find it you'll have to web-search(copy & paste) this article headline instead:
"Solid State Battery with great Environmental Performance and Longevity".

Manufacturing QS batteries may not be that big of a problem. The problem most likely will be cost vs Tesla's 4680 battery that theoretically will provide ~350Wh/Kg at ~half the current cost of the 2170 cells. Can QS compete against Panasonic golden egg batteries for Tesla, that's my question?

LFP, NMC and Sulfur based batteries are a different ballgame. Most Tesla batteries are NCA, though China seems to have allowed them to use LFP batteries o in some newer Model 3/Ys. This will have impact on how this market develops

If QS can compete in cost and reliability (reliability takes time to prove, the same goes for 4680). Then QS might have something. (Ask GM, and all other ev manufacturers if it's easy to compete against 2170 cells??? Forget 4680s).

Though if QS or Panasonic/Tesla could reach 450Wh/Kg, now that's a game changer regardless of cost before someone else beats them to this market. That implies that planes can use them!. Planes need over 400wh/kg to become viable. And so can long haul transportation vehicles (trucks/ships/defense). There are new VC backed initiatives that target this market with over~400wh/kg @10-20A, today!.

Current QS technology has potential to affect at least electronic products, will it affect vehicles and transportation, defense sectors as well, that remains to be seen.

Discloser, I'm long on QS and thinking about TSLA.

Add to cart! Didn't think so.
