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