AltEnergyInfo: UCLA lab’s accidental discovery could lead to dramatically reduced charge times for electric cars

Researchers at UCLA, while trying to figure out a way to mass produce graphene, an extremely thin pure form of carbon, have created a supercapacitor that can be charged quickly and can hold much more electricity than standard batteries. And the same research team now feels that they’ve found a way to mass produce these supercapacitors. Researcher Maher El-Kady at UCLA’s Kaner Lab developed a way to easily make sheets of graphene one single carbon atom thick by coating a DVD with a liquid carbon solution and sticking it in a standard DVD burner – the laser did the rest. But somewhere along the way, he discovered that this single sheet of graphene could hold a lot of electricity and could be charged extremely quickly. So the team found a way to embed electrodes within each graphene unit on a flexible backing – each supercapacitor is bendable, making them potentially useful f...
