Reasons I'm suspicious:

* article leads with "in production" but it sounds like they are still at the design phase. production of prototypes maybe?

* they are doing a lot of "talking" and "partnering" but not so much selling mentioned.

* they are "known for" their similar work in the ultra-capacitor market but the linked page's top comment is "still waiting for a product".

* PR about raising funding and starting soon but not a lot of PR about actual products and results.

Am I being too cynical - does anybody know if they are for real?

"If its too good to be true..."

Its healthy to be skeptical until an extraordinary is proven.

Meanwhile can I interest you in investing in my hydrogen truck company called TeslaNikola? Its carbon free, costs close to nothing to run. We have a working prototype capable of going downhill.

IF this is true, it would be a massive breakthrough. Truly monumental. Hence, I am skeptical.

But otherwise, this would be a massive thing. a 2x capacity per weight advantage of batteries? Without an increase in space? That comes down to doubling the range of EVs, and making electric planes and rockets a lot more viable.

A 3x capacity per space advantage means roughly a 3x improvement in your phone and laptop battery capacity. Or, more likely, a slight improvement in your phone and much thinner phones. On laptops, we might see the return of more ports.

A 10x speedup of charging? That makes all-day EV travel a lot easier. It makes topping off your phone something you can do a minute at a time, rather than an hour long process. It means, with wireless earphones, you can re-charge them in a minute and almost never be without them.

If even a third of what they claim here is possible, it would be amazing.

The author probably doesn't know how we read articles like this. A wild discovery in it self is fun but one doesn't expect to see products (anymore/any-time-soon).

Then towards the end he writes: "The company has moved past its pilot unit and now has a full production unit up and running"

:o

Too bad Nikola Tesla didn't had a middle name.
