A facile approach was demonstrated to prepare ZnO/graphene (ZnO/G) composites for supercapacitor materials.The structure of ZnO/G was examined using Powder X-ray diffraction (XRD).The electrochemical performances of these electrodes were analyzed by cyclic voltammetry.The results showed that the ZnO/G composites displayed superior capacitive performance with large capacitance (139F/g).
