Abstract
Supercapacitors have composite electrodes that include a porous carbonaceous material such as graphene onto which a metal oxide pseudocapacitor material is deposited in the form of nano-scale particles or a nano-scale film. The composite electrodes exhibit excellent specific capacitance, even at high scan rates.
