The electrochemical properties of graphene make it an attractive material for use in a range of devices. We herein describe the simple preparation of graphene‐modified graphite (GMG) composite electrodes by hybridization with graphite for all‐vanadium redox flow batteries (VRB). The cyclic voltammetry (CV) results revealed that the use of GMG composite electrodes with an optimal graphene loading content (3 wt%) allowed remarkable improvements in terms of both the reversibility and the current density, which was up to 30 % higher than that of the pristine graphite electrode, and that an electrode of this type shows considerable potential for use in VRBs.
