This is what coming in the next generation of batteries...

Graphene Batteries with properties to eliminate fossil fuels

especially in transportation.

That sounded like someone looking for investors.......If all he said was true, why was it not heralded from the rooftops by every major news network?

I'd trust the guy more if he took off his sunglasses. The video did not over-hype graphene batteries as much as I expected. But it was vague as to the current state of development. Is Gruber testing graphene electrodes to enhance "conventional" LI batteries? Or are they testing the real blockbuster -- full-blown graphene super-capacitor batteries? I couldn't really tell, but it sounded like the electrodes, which is not the huge payoff.

Don't scoff, though. A little internet searching turns up lots of development efforts, so it's a real thing. Next year? Next decade? It sounds promising. Who believed in the transistor in the early 1950s? And who even dreamed of miniaturized integrated circuits then?

This article (link below) is almost ten years old, so I have to believe there has been progress since then.
Maybe Gruber really WAS talking about the good stuff?

Yeah, I took 30 min that I will never get back and read all about the new flying car. Googled it and got half dozen adds from Amazon trying to sell me something....No doubt, the potential is there. I remember reading about Graphene many years ago in Discover magazine. But here we are 30 years later and they are still talking about the potential......

The thread right under this at this moment is FF copper one. Maybe we should get some of that "cured copper" the Amish use to make electric heaters that magically put out more btu's then the electrical energy put into them. Maybe the Amish discovered graphene first.....

I don't see how EV's can achieve any kind of economic viability or achieve green objectives without a dramatic reduction in battery weights. AFAIK, EV's currently are substantially heavier than equivalent ICE-powered vehicles, so as a matter of physics they require more energy to move, and put more wear on the roads. Without big subsidies, and with paying their way on infrastructure costs (such as replacing gas tax with some form of mileage tax?), it seems like they need some kind of home run on battery technology to get the weight down.

700 miles with 15 minute charge would pretty much be a triple, if not a home run. If the weight is low enough. I looked into converting a car or pickup truck to electric, back when the only affordable battery choice was lead-acid. As I recall, the more you tried to extend range, the behinder you got, because so much of any increase in battery capacity went to hauling the added battery weight.
