1Surface modification by graphene oxide:An efficient strategy to improve the performance of activated carbon based supercapacitors显示文摘We demonstrate an efficient and cost-effective strategy to improve electrochemical properties of AC based electrode materials. A series of graphene oxide(GO)-modified activated carbon(AC) composites(GO@ACs) have been prepared as electrode materials for supercapacitors(SCs). In GO@ACs, AC particles anchored on the surface of GO sheets which were synchronously reduced during charge/discharge process, and formed a 3D-conductive network. Electrochemical analyses revealed that 2.5 wt% GO@AC,which exhibited improved electrical conductivity and high specific capacitance at large current density in organic electrolyte, is a promising electrode material for high-performance SCs. At 6 A/g, the specific capacitance of 2.5 wt% GO@AC increased by 249.5% in comparison with that of AC.Weishi Du Yaokang Lv Hongliang Lu Zaihua Chen Dominic S.Wright Cheng Zhang 2017Chinese Chemical Letters2017,28,12:1
