Abstract

•This is a new method by electrophoresis to introduce metal onto carbon materials.•It enables to adjust the metal loading and size uniformly.•The highest capacitance of Ag/Gr-0.10 is 273.6 Fg−1 (at 0.3 Ag−1).•This appeared to have a 2.5 times later than the crude Gr.

This study evaluates the excellent electrochemical performance of silver (Ag)-coated graphene electrode using an electrolytic deposition technique. Ag particles are introduced to the graphene surface as a function of the applied current. A half cell of the Ag-coated graphene electrode is fabricated to examine the electrochemical performance, such as the charge–discharge behaviors, cyclic voltammetry, and specific capacitance. As a result, the electrochemical performance of the Ag-coated graphene electrode is two times higher than that of the crude graphene electrode.
