That article gave no reason for me to believe these claims. Also that website is horrible.

Fluff piece for getting funding from suckers.

[–] [email protected] 2 points 9 months ago

Interesting the major backer is Volkswagen who announced last week their brand is no longer competitive...so now they're trying to get more value out of this investment by junk pieces like this.

It's solid instead of liquid broski. QED.

Lots of companies have been saying they have solid state EV batteries for years, yet you still can't buy one. Either they can't figure out how to mass produce them cost effectively or there is some sort of problem with the battery.

I think toyota actually plans on getting there in the next few years. I think the current and final hurdle; which I'm guessing a couple different companies about have a complete handle on is the prevention of dendrites forming and causing the batteries to go bad from multiple charge cycles.

Toyota wouldn't be blowing fluff about having the batteries a few years away from production if they weren't confident about it happening. That's reserved for saying something is 7 to 10 years away.

[–] [email protected] 15 points 9 months ago (3 children)

I think it's more likely that Toyota dropped the ball on not investing in EVs early, so that they felt the need to announce they were working on some thing in hopes of staying relevant.

[–] [email protected] 7 points 9 months ago

Toyota has been claiming to have EV-killing tech 3-5 years away for 20 years. It's part of the plan for selling hybrids.

I mean…. Really? Toyota kind of kicked off the whole EV shebang by introducing the first commercially successful hybrid in the Prius. And they’ve been innovating in the space ever since. Don’t mistake this for me believing they have a solid state battery right around the corner. But Japanese auto companies aren’t known for being on the forefront. They’re known for doing what everyone else does with better reliability and lower costs.

[–] [email protected] 7 points 9 months ago (2 children)

Toyota have announced several times already that they're "this close" 🤏 or only a few years away from releasing their first solid state battery EV...I'll believe it when I see it.

[–] [email protected] 5 points 9 months ago

Me too. And their revolutionary hydrogen car that everyone will turn to by the year yesterday

The same Toyota that declared that electric vehicles were a non-starter and that hydrogen vehicles were the future?

I think hydrogen will be in the future, but not for a while. Toyota is having to make lots of promises to make up for Kia and Hyundai eating their lunch.

Toyota doesn't make batteries, they make press releases - the purpose of which is to dissuade you from buying a BEV, in case you find out how good they are.

[–] [email protected] 1 points 9 months ago (1 children)

Here's why I don't buy it- Toyota is still hyping hydrogen as the next gen fuel option. They barely have a BEV option, despite having a 15-year lead on electric drivetrains.

They're betting hard that BEVs are a small market.

Tell me once it's on the market. Been reading about better battery technology for years, and nothing happens.

Battery capacity has tripled in the last decade

Yeah, I think I've lost track how many articles and youtube videos about amazing "solid state" batteries are just around the corner. But I've not seen one actually materialise.

I mean, it's great if true. But, I'm going to wait and see.

There's been a steady increase in lithium based technologies though. But I do wonder when and where the plateau there might be.

[–] [email protected] 1 points 9 months ago* (last edited 9 months ago)

Lithium Ion based batteries have a lot of room to grow still.

Everything out there in cars today can likely still double or triple over the next couple decades.

Everyone says they want a 1000 mile car but they really don't need it. We'll reach an optimal price/battery range in a car and begin reducing the amount of batteries with our current tech before we're selling cars with the full potential a decade or two from now.

And the increase in power density in LFP batteries will be a great thing given their cost, longevity and safety profile.

[–] [email protected] 49 points 9 months ago (2 children)

Wake me up when they’re being mass produced at cost effective rates.

And can dissipate heat efficiently in the same package size. The limitation to lipo/life/li-ion package density isn't cell volume. It's cell volume plus heat removal overhead. Making the cells smaller doesn't actually change anything about the cooling overhead.

[–] [email protected] 48 points 9 months ago

LMAO They are going to win!

They beat Tesla with their own weapons: empty promises!

Maybe we need to have a completely-bullshit-venture-capital-investor-bait-technology community.

Yah and cold fusion is right around the corner.

[–] [email protected] 22 points 9 months ago (1 children)

Awesome I can use that to charge this new battery

[–] [email protected] 3 points 9 months ago

You’ll want a Mr. Fusion for that.

[–] [email protected] 44 points 9 months ago

So does this company actually HAVE a solid state battery or is this still all in concept?

Because we already know how amazing and good a solid state battery would be... When we finally get them. But the problem is actually getting them.

Unfortunately the article seems to be mostly talking about how good a solid state battery would be and not much at all on this startup actually having anything functional.

[–] [email protected] 30 points 9 months ago

Great, I guess I will just go to a store a buy one of those .

[–] [email protected] 21 points 9 months ago (1 children)

Ah yes more "crushing" tech... High density and fast charging... Always means it's only good for like 100 charge cycles so it's effectively useless in reality.

[–] [email protected] 7 points 9 months ago* (last edited 9 months ago)

from what i understand, solid state batteries are legitimately about as revolutionary as lithium ion were because they are all of those things, and by their very nature they have a huge number of charge cycles

… whether this specific announcement results in a mass-production-capable battery is another story

[–] [email protected] 19 points 9 months ago (1 children)

QuantumScape has been expected to produce something for a long time now, it isn't new, the article didn't mention timelines or production.

They where supposed to go intro production mid this year / next

Till we see them rolling off the factory line it is just vapor .

The Next Big Thing™ is always ~5 years away.

[–] [email protected] 18 points 9 months ago

Battery news have been so fake every time. I won’t believe any more battery tech news until I see an actual device or vehicle powered by one.

[–] [email protected] 11 points 9 months ago

We know solid-state batteries are good, we want someone to produce stable solid-state batteries cost-effectively.

[–] [email protected] 9 points 9 months ago (1 children)

Yes, I'm going to base my investment on large scale technology on finance.yaoo.com, or better yet benzinga.com!! Especially after their exclusive on "Analyst Inside Look: Trends And Opportunities In Ohio's Emerging Recreational Cannabis Sector"

But this battery CRUSHES it! That's more than SLAMS!!!

[–] [email protected] 2 points 9 months ago

I keep reading batterie breakthroughs that change the world for decades now.

[–] [email protected] 6 points 9 months ago (1 children)

First of all, their claims are not new. They claim this for a long time already but have not shown a minimal viable product yet. During the time they spend money in research, Tesla batteries grew to 3 times the originals.

QuantumScape have only shown minuscule batteries, they need to scale up to car battery capacity. Only a car with their battery can prove their claims. Until that happens their stories are worth nothing.

Charging a 75kWh large car battery in 15 minutes requires a charger of at least 300.000W. Imagine a charging station for 5 cars would need a 1.5MW power station. That is impractical. Also the current flowing into the car would be enormously high, requiring huge cables. Also inside the battery pack, huge cooling systems are required.

More practical solutions are exchanging battery packs or battery fluid exchange (flow battery). In short time 100% recharge and virtually unlimited range if packs are slowly charged at exchange hubs. .

QuantumScape will water down their claims and eventually publish a more or less standard LiFePo battery if the investors are lucky.

[–] [email protected] 1 points 9 months ago

Thanks for your insightful comment.

Regarding 300kW charging: I thought new EVs already charge with up to 180kW DC (?), so this would "only" be a doubling in performance?

[–] [email protected] 3 points 9 months ago

Is there any proof ? I've seen a single article. Nothing if substance. QS has been saying for years it will beat Tesla. Last earnings meeting had nothing to show. Was burning cash and keeping of research. That's wasn't too long ago.

[–] [email protected] 2 points 9 months ago

Toyota said they are aiming for 2027 or 2028 with their solid state tech. I'm amped for when it comes but it's not really fair to compare potential 5-years-out tech with present day tech.
