| Abstract: | To improve the electrochemical properties,graphene which was made by improved Hummer was modified by manganese dioxide.XRD was used to research the crystal structure of composites.The performance of electrochemical capacitors was investigated by cyclic voltammetic,alternating current impedance,and constant current charge/discharge tests.The results showed that the electrochemical properties of graphene which was modified by MnO2 was improved obviously.It had an obvious pseudo-capacitance effect.The specific... |
