Higher energy density

Nobody's demonstrated this in real life yet.

which means more power in a smaller size and weight.

You're conflating two metrics, which doesn't bode well for this conversation. Gravimetric and volumetric densities are different, and so far solid state batteries don't have an advantage on either front. The hope is that they will have a gravimetric density advantage at some point, but not necessarily volumetric.

Higher safety

I've already explained to you that existing LiB cells use non-flammable electrolytes, so this isn't an advantage. You're a decade behind the state of the art.

Shorter charging times

Which again hasn't been demonstrated by anybody in real life yet.

as the solid electrolyte allows faster movement of ions.

Intercalation is still the slowest part of the transfer, and solid electrolyte does nothing for that. What might improve that is polymer doped cells, but so far that's been another complete disaster.

A wider range of operating temperatures

Again the electrolyte is only a part of this equation. And while it doesn't freeze like older LiB electrolyte would, we're so far past this problem in most applications that nobody even cares anymore.

Longer lifespan

Nope. Every demonstration so far has VASTLY shorter cycle lifetimes, which is further exacerbated by the worse gravimetric density. I'm really not sure where you do any of your research, but reading press releases is rotting your mind with marketing hype.

From the people who are putting their money into it.

Then, why do we need a solid-state battery? It is to increase capacity of EV batteries.

Market research companies expect that EVs will replace ICEVs(internal combustion engine vehicles), and become the mainstream in the auto industry. And to become the unarguable leader in the industry, EV should have the similar level of mileage as the current ICEV, and it is important to increase the battery capacity of an EV battery to do so.

There are two ways to increase capacity. First is increasing the number of batteries. But in this case, the battery price goes up and batteries take up so much space in the vehicle.

A solid-state battery has higher energy density than a Li-ion battery that uses liquid electrolyte solution. It doesn’t have a risk of explosion or fire, so there is no need to have components for safety, thus saving more space. Then we have more space to put more active materials which increase battery capacity in the battery.

A solid-state battery can increase energy density per unit area since only a small number of batteries are needed. For that reason, a solid-state battery is perfect to make an EV battery system of module and pack, which needs high capacity.

You seem to be of the belief that no new battery tech ever reaches the market, which is obviously false. There is a lot of work going on to bring this to market. The truth is neither you or I know whether this will happen.

My bet is someone will crack it 👇

On fact LFP is "new" and it's selling. My take is that idiotic developments with three decades of failure don't reach the market.

Not with that sort of attitude. How long did it take solar to scale?

[-] drdabbles@lemmy.world 0 points 10 months ago

Not long at all, but the challenge isn't the same. Again demonstrating you don't understand the topic.

[-] bernieecclestoned@sh.itjust.works 1 points 10 months ago

But the people who do, are building pilot production lines. Why?

[-] drdabbles@lemmy.world 0 points 10 months ago

They aren't though. You can't tell the difference between PR, Marketing, and real life.

[-] bernieecclestoned@sh.itjust.works 1 points 10 months ago

They are though. Have you any idea of the capex involved in a 65,000 m2 facility?

In March 2022, Samsung SDI announced that it would set up a trial production line for manufacturing solid-state batteries in Yeongton-gu, a district in the South Korean city of Suwon. The production line, which is named the “S-line”, would take up an area of 65,000 square meters.

Notice how that article is from July, and they didn't report progress on such a line? Odd, no? Surely in four months the tense would have gone from "will" to "is", right? And yet...

[-] drdabbles@lemmy.world 0 points 10 months ago

You see how this article, published in October, is ALSO future tense? One should wonder why if they've started building a factory line in March, there's been no change in tense, or note on progress. Hmmmm. You just made my point for me. Thank you.

[-] bernieecclestoned@sh.itjust.works 0 points 10 months ago

Completed. Do you understand business planning? Product road maps? How anything gets done?

The company has currently completed the pilot line for solid-state batteries within its Suwon Research Institute and is deeply engaged in securing mass production technology.

I think you're gullible, and that's about the only thing this thread has revealed. But you go on believing fairy tales, it makes zero difference to me.

[-] bernieecclestoned@sh.itjust.works 0 points 10 months ago* (last edited 10 months ago)

Lol, so when I show you a completed 65,000 m2 pilot line, it's a fairy tale.

People who don't change their minds when presented with facts are rigid minded fools.

I guess Samsung and >10% of their R&D budget and all the other R&D scientists must be wrong and some opinionated condescending twat on the internet must be correct 😂🤡

Now get back to your shitty tech support queue, those printers won't switch themselves off and on again.

[-] drdabbles@lemmy.world 0 points 10 months ago

Now look who's the condescending cunt. Wow. What a gaping asshole you are. Even if I was on printer support, I'd be a better person than you, sou sniveling waste of air. You didn't show shit, you posted marketing bullshit. Which is what I expect from a know nothing loser that thinks they're above other people. Only the lowest of low think that way, and I couldn't care what someone like that thinks.

Enjoy your miserable life, you'll never be happy thinking you're better than anyone else.
