Supercapacitor is a new type of energy storage device between a conventional cap secondary battery due to high power density, long cycle life and fast charging/discharging rat acitor and a e. Superca- pacitors have been widely used in communication devices, hybrid vehicles, aerospace and many other fields. Electrode material is an important factor that determines the electrochemical performance of super- capacitors, which has been explored extensively recently. Carbon-based electrode materials have great application prospects in supercapacitors because of their high yield, low cost and good electrochemical performances. Hence, this review introduces the preparation of carbon and carbon-based composites and their applications for supercapacitors recently.
