Ultracapacitors: Graphene gadgets
Abstract
Electrochemical double-layer capacitors, otherwise known as ultracapacitors, have been proposed as energy-storage devices that could absorb and release power almost instantaneously. Rodney Ruoff and colleagues at the University of Texas, Austin, have illustrated one way that this goal could be achieved, by including flakes of graphene — one-atom-thick sheets of carbon — in the capacitor electrodes.
