The graphene sheets were prepared by Staudenmaier method in this study, and were used for the electrode in supercapacitor. We chose ionic liquids as electrolyte for their wide potential window to get better energy density and power density. First we chose graphene (GNS-300) which is made by raising temperature 1℃ per 1 min to 300°C.
