Graphene based materials are considered as a promising energy storage materials due to high specific capacitance, superior conductivities, large surface area, and mechanical properties. Therefore, the hybridization with 3D graphene is fascinating in that it can take advantages of graphene. In this work, Nickel contained nanoparticles are branched on the surface rGO nanosheets for an application into high capacitive supercapacitor. The precursors of Nickel nanoparticles are intercalated to the layers of rGO sheets and directly converted to metal oxide through the nucleation and growth induced by the microwave irridation. Since the carbon nanotube branches are growth directly on the surface of the carbon nanotube or graphene, excellent interface characteristics can be realized and 3D carbon structure can be obtained in a short time due to microwave synthesizing method. According to these features, it can provide synergetic affect on the energy storage for high capacitive supercapacitors.
