Activated carbon has been used widely as the supercapacitor electrode material for its easy availability, low cost, high specific surface area, excellent electrical conductivity and chemical stability. The working principle of supercapacitor with activated carbon as electrode and effect of physieochemical properties of activated carbon on electrochemical performance of supercapacitor are discussed, recent research advances and application prospect of aeti- vated carbon electrode material are highlighted. The focus of future research such as search for new raw materials and activation technology for activated carbon, exploring an effective method to control the pore struelure and surface properties of activated carbon and development of activated carbon composite are also pointed out.
