In this work we identified the electrochemical performance after decorating Ag particle on graphene surface. At first, we manufactured graphene oxide using Hummers way. Then, we are producing a paper of graphene oxide by mixing potassium nitrate aqueous solution and graphene oxide. And then, we manufactured graphene through chemical reduction on that graphene oxide. That graphene film introduced Ag particle appeared high electrochemical performance than graphene. To find electrochemical performance, we manufactured half cell of graphene decorating Ag particle which we made and conducted electrochemical performance test such as charge-discharge test, cyclic voltammetry and specific capacitance. As a result, we could find the superiority over twice on electrochemical performance when we decorate Ag particle not graphene. |
