Graphene Ultracapacitors Offer Blistering Performance and Charge in a Couple of Minutes
Researchers at the University of California are developing graphene supercapacitors that can charge and discharge in a couple of minutes. The ability to discharge in a couple of minutes means that they are extremely powerful. More importantly though, these researchers developed a technique for printing graphene supercapacitors using a DVD burner.
The researchers dissolved graphite oxide in water and heated it with a laser from a standard DVD burner to obtain flexible graphene sheets. These graphene sheets are one-atom thick, yet can hold a remarkable amount of energy, while being charged or discharged in very little time compared to standard batteries.
Ultracapacitors have tremendous advantages over typical lithium-ion batteries, some of which are of paramount importance to the adoption of electric cars, such as their ability to charge in as little as 1 second, and last 20 years (easily, and with very heavy usage).
