Whoa, 12kwh/kg is the energy density of diesel fuel.
Chemical energy, no engine losses considered...

If that's real, then aviation is about going to get electrified...

I wouldn't be so sure.

First, CATL is a Chinese activity, well-known across industry to be fueled with the end products of industrial espionage- I wouldn't trust their shit to power a flashlight.
Second, even this group openly concedes that 12kWh/kg is purely theoretical at this point, as their current prototype arrays are only doing a tenth of this projected performance. They have a long way to go.
Third, hype is all good with a proven product that's market-ready, but when false hype on YT by third-party fanboys & influencers flood the space, it does far more harm to any advances in the state of the art than it does good.

It’s my understanding that Aluminum-Air battery infrastructure wouldn’t have the same energy density - but would be so much cheaper to manufacture and implement as an exchange network, that it might very well be worth it.

Aluminum oxide?

The problem with that is it bonds so tightly that reversing the process is miserable.

Yeah I’m fuzzy on the specifics - and it was a few years back and I haven’t heard any updates lately. Aluminum oxide is indeed a pain in the ass - which I believe is part of why they pitched it as an exchange because recharging is beyond what consumers can normally be expected to afford.

>Aluminum based nanogalvanic alloys
>alloy powders have also been considered as an alternative energy source for batteries (coupled with fuel cells). Demonstrated to produce 1000 ml. of hydrogen gas per gram of aluminum in less than 1 minute and 1340 ml—100% of the theoretical yield at 295 K and 1 atm.—in 3 minutes without the need for hazardous or costly materials, or additional processes. Approximately double rate of reaction in urine.

Basically can make a fuel pack from aluminum dust made from machining byproduct. It is very good for creating hydrogen. Since hydrogen fuel cells produce water, it could feed itself and not need much. Or a drone could land and open its hatch and passively gain water when rain hits it and start the reaction.

My dude. If energy density is that high, why doesn't the MIC sell $20,000 hand grenades to the military. Its the ultimate self licking popsicle for clean energy niggas

Aluminum, like coal, has a better energy density than C4, but they release their power slowly because they require oxygen from the environment. C4 carries it's own oxygen so it can release it very quickly.

There’s a certain poetry that it runs better in piss; final validation for jarate enthusiasts
