Successful solid-state battery?

[Borg]

An interesting article about a new solid-state battery that would have a huge list of positives if the details in the article are true - cheaper to make, able to hold more energy per pound, have more charging cycles, extremely quick charging, and virtually no heating issues. And according to the article, they are already in production. I'll look forward to see if it pans out.

For its solid-state batteries, Donut Lab is listing some incredible figures. To start with, there’s an energy density of 400 Wh/kg, which is about a third greater than that of a modern lithium-ion pack. In other words, 30 percent more range in an EV with the same weight battery pack.

Despite that boost, Lehtimaki says these cells are actually cheaper to manufacture. These batteries will appear first in the Verge TS Pro, and Lehtimaki told me that swapping to these hyper-advanced new cells actually reduced cost.

“The bill of materials went down, and it is going down with every other vendor buying at the rate that we are selling them,” Lehtimaki says.
Donut says the batteries can take a full charge in as few as five minutes, which would finally mean an EV that charges as fast as you can fuel up a car.

It claims to be a massive improvement in almost all aspects, which of course is reason enough to take this with a grain of salt until the claims have been independently verified and published.

That said, people are of course already trying to dig into as much detail as possible. For example youtuber Ziroth, who I understand generally reports on new technology and claims to have ph.d. background in battery technology, so far thinks there is indication that the battery (if it is valid) may in fact be a capacitor, likely based on the capacitor nanotechnology developed by Nordic Nano and later investment aquired by Donut Lab:
