In this work we investigated to electrochemical properties of mechanochemically prepared graphene oxide by physical technique. We have prepared mechanochemically synthesized graphene oxide by physical technique. To compare the graphene oxide in this study, graphene oxide was prepared by chemical method (Hummer’s way) that was well known. The prepared two graphene oxide samples have been characterized by XRD, SEM, and BET. To study electrochemical performance, we prepared half cell of graphen oxide and conducted electrochemical performance test, including charge-discharge test, cyclic voltammetry, and specific capacitance. As a result, We could find that the mechanochemically synthesized graphene oxide was higher electrochemical performance than the chemically synthesized one. |
