Great news! Already invested in Rio Tinto

9 out of 10 of these press releases are of something that doesn't pan out. Companies spends shiite piles of money on brand new plants where the process worked in the lab and at pilot plant but never do at full scale.
I well remember the revolutionary new plant to skip steps in going from bauxite to aluminum metal. Damned thing made shiite tons of fully chlorinated PCBS's, but that never happened in the lab or pilot stages. Alcoa, Palestine, TX

Also, getting 600 miles per charge in an electric car and being able to recharge in 10 minutes is a game changer.
That ain’t happening unless you’re boosting power from a substation.
At those charge speeds, your electrical infrastructure becomes the limiting factor. Charging an 80 kWh battery in 10 minutes, even at 100% charge efficiency, would require a 480 kW load. That’s significantly more than residential transformers are rated for. It would draw 2,000 amps at 240 VAC.
ETA: Just to be clear, even with the current Li-ion car batteries, the limiting factor for residential charging is electrical load. Faster charge times would primarily benefit the smaller batteries in consumer electronics.

The residential speed is really not the big issue, the vast majority of residential recharging is done overnight. The Tesla Supercharger 3 is rated at 250kW but they aren't in widespread use yet. You lose about 25% in the charging process the majority of that in rectifying AC to DC.
If/when we have EVs in the 600 mile range if you can get 200 more miles in 20 minutes or so that will cover almost all of the driving needs of all but a tiny percentage of drivers. Also when Interstate driving is basically autonomous even an extra hour to ones 1000 mile trip won't bother most drivers as they will still arrive far fresher than after driving for 13-14 hours.

Added to my watchlist. Thanks!

Fusion is the answer...

So the Tesla Plaid is already obsolete?
Posted on 6/13/21 at 7:21 am to NPComb
I am thinking Tesla planned on innovation in battery packs and in turn made their batteries modular and replaceable. If anything could be obsolete it would be the battery and not the car.

Yeah, that's not going to happen without high temperature superconductors and significant upgrades to the electrical infrastructure at all levels.

I can’t wait to see how this turns out in 20 years.

Graphene is a new technology. All new technology is expensive initially. They will figure out how to mass produce it cheaper. Cotton was a lot more expensive before the cotton gin.

On a small scale. There will eventually be a breakthrough in production

I've been hearing about all of its amazing tensile strength and thermal properties for years and years now, and the excitement of the public behind the "wonder material" seems to have waned.
I'm guessing scaling production has been a bitch and a half.
