Supercapacitors are energy-storage devices which obtain energy from the electrochemical double-layer or the redox-type reactions at or beyond the surface of the electrode. They possess high power density and energy density, and have a long life cycle. This review will survey the fundamental principles, characteristics and applications of electrode materials for supercapacitors, with special emphasis on the recent progress of research on graphene, manganese oxide and their composites as electrode materials.
