Yes, that’s what is reported in this article.



Given that the source is a publication for oil traders, I’m skeptical that this might be a planted story meant to raise hopes, so that they can be dashed again and shift people back into oil futures, by which time the traders will have cashed in on suppressed prices and make a killing.

So, do any of our U.K. members have knowledge of the technology or company mentioned in that article? Is there real hope here or is it the nexus of a burgeoning scam?

"...our current (Gen 3) cells perform about three times (3x) those of conventional supercapacitors."

They're seemingly guilty of perhaps-intentionally conflating batteries and supercapacitors in their marketing. They're also seemingly guilty of making promises based on Gen 4, Gen 5, and Gen 6 (which presumably do not yet exist, since the Gen 3 are explcitly noted as currently existing).
 
Yeah, sounds dubious. Assume a 55 kWh battery/stacked capacitor and, say, 120V charging voltage, that requires 47 kA of current. A half-inch diameter wire carries about 300A, so we would need 160 such wires to carry the charging current. That's about a 7 inch cross section cable.

Another load of twaddle about the electric cars.

At the moment the only company with a sort of plan is Tesla where you pull into a service station, drop your batteries and install a fresh battery pack. amount of effort would seem to be akin to changing wheels on your car.

At 1.5MVA that's roughly the same as a housing estate in the UK consumes. Where exactly is all of this spare power coming from?

Very early petrol car owners used to pull into a chemist job to buy a bottle of petrol. Look to today and there is a huge infrastructure of filling stations and distribution for petrol and derv. I can't see this infrastructure for electric cars. People are trying to plug into their domestic supplies, street lights and at 'fast' chargers at the supermarket.

There is a long way to go to make electric cars viable but I think it has to happen.
