Re: Vertically aligned carbon nanotubes triple the density of lithium batteries
#2Wow, if the coating is so cheap perhaps it can replace activated charcoal elsewhere, too. Would it also triple the capacity of water filters?
Re: Vertically aligned carbon nanotubes triple the density of lithium batteries
#3Reasons 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.

#5The rule of thumb is that battery density increases by roughly 8% per year. Expect this to go into production in 15 years.

#6IF 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.

#9A 3x capacity increase is huuuge but a >10x cost increase is prohibitive except for applications like aircraft.

#10Didn’t Maxwell Technologies already announce a similar breakthrough a few years ago, and isn’t that why Tesla bought them?
Some patent lawyers are going to wake up to some good news today...
