▎ 摘　　要

In this paper, the electrochemical performance of the supercapacitors with graphene as their materials was studied. Graphite oxide were prepared by modify Hummers method. Then graphene were obtained that GO as the precursors rapidly exfoliated at the temperatures of 400 degrees C under nitrogen atmosphere. The capacitance can reach to 342 F.g(-1) at the current density of 1000 mA.g(-1). The graphene exhibited an enhanced storage capacity as electrode material in Supercapacitors.
