ABSTRACT
Among all kinds of energy storage devices, supercapacitors are very important power type and their performance is largely dependent on electrode materials. Porous carbonaceous materials are extensively used as electrode materials in supercapacitor owing to their unique features, such as large surface areas, fair electrical conductivity, and abundant pore structure. Rational modification of carbonaceous materials offers opportunities to further enhance their electrochemical performance, leading to high energy density and power density for supercapacitor. This chapter reviews the recent progress on different porous carbonaceous materials including graphene and carbon nanofibers in supercapacitors. Also, the brief history of supercapacitor, future development and the characterization of carbonaceous materials will also be introduced.
