This is really interesting. Thanks for posting.
One thing that seldom gets mentioned in discussions of super fast charging of things like electric cars, is the infrastructure and risks involved in pumping the necessary amount of energy into the car or whatever. If an electric car with a similar range to a gasoline powered one is to be recharged "in minutes" then that means some huge wires, lethal voltages, or both. The charging station will need its own electrical service, probably bigger than that on the typical American house, and the car's onboard components will have to be up to the task. That translates to heavy, bulky, and expensive. None of this is easy. The batteries are about half the battle, in terms of engineering a car that will run and "refuel" like a gasoline powered one. Of course gasoline is volatile, extremely toxic, smelly and prone to explosion if not handled with care. That's all mitigated by decades of development of the infrastructure. It's going to take a while for electric cars to catch up. I'll be happy when they do, if I'm still around to see it, because they offer many advantages.
Charging a laptop in a minute or three will not be a big deal, except the charger will likely draw as much current as a toaster.

Maybe, but assuming that current draw lasts a minute or so, or is spread out over a three hour charging session, what difference would it make?

It's that pesky Ohm's Law again! But it can be thought of in terms of scale: You can fill a swimming pool with a garden hose, but not in an hour. You can charge your electric car with an extension cord, but not in an hour.
Most people don't have any reason to be familiar with just how much energy a tank of gasoline holds. The energy density of gasoline and diesel fuel (essentially kerosene) is extremely high. It's what makes things like jet planes feasible. The energy density of typical batteries is comparatively very low, so they take up a lot more space in a car than a fuel tank, and weigh a lot more. Ten gallons of fuel can be squirted into the tank in a few minutes. To deliver an equivalent amount of electricity, in a similar time, takes some scary equipment. In an industrial setting, it's just money and space. To replace a gas station with an electrical charging station of similar capacity, it's a big deal, especially in terms of safety. An idea of what can go wrong can be gotten by watching some of those videos of exploding substations, arcing high tension switches, and so on. Even the small ones are catastrophic. Imagine you and your car in the middle of that.

I don't know squat about dual carbon batteries. But I assume that, like all other batteries, they have an internal resistance. This acts like resistance inherent in any electrical component--simple wire, resistors, electric light bulbs etc. They all have one thing in common: The more current you pump through them in a given amount of time, the hotter they get. This sounds like a walloping amount of current generating heat that must be dissipated somehow.
Dunno....maybe they have it all figured out.
