Fig. 2 presents the diagram of the solution coating process for the G/CF. Firstly, the commercial CF was washed with DI water and ethanol three times before being died at 60 °C. Then the graphene/Nafion (225 mg/25 mg) mixed solution (DMF/NMP = 50 mL/450 mL) was prepared according to the process described in the experimental section. In the following step, we immersed the CF into the graphene/Nafion solution for different dipping times, and then different amounts of graphene and Nafion were

Graphene deposited on the surface of a carbon felt (CF) using a solution coating method has been developed as a high-performance positive electrode for an all vanadium redox flow battery (VRB). A key to obtain excellent electrochemical activity towards the VO2+/VO2+ redox couple is to wrap the CF using the graphene with high specific surface area and superb conductivity. It is found that the dipping times of CF into the graphene/Nafion solution significantly affect its electrochemical activity. The cyclic voltammetry (CV) results indicate that with 5 dipping times, the graphene coated CF (G/CF...
