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 πŸ‘‡

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 1 year ago (1 children)

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

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

[–] drdabbles@lemmy.world 0 points 1 year ago (1 children)

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

[–] bernieecclestoned@sh.itjust.works 1 points 1 year ago (1 children)

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 β€œS-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...
