Abstract
A surface-modified nano graphene platelet (NGP), comprising: (a) a nano graphene platelet having a thickness smaller than 10 nm; and (b) discrete, non-continuous, and non-metallic bumps or nodules bonded to a surface of the graphene platelet to serve as a spacer. When multiple surface-modified NGP sheets are stacked together to form an electrode, large numbers of electrolyte-accessible pores are formed, enabling the formation of large amounts of double layer charges in a supercapacitor, which exhibits an exceptionally high specific capacitance.
