Nafion membrane has been widely used in fuel cells due to its good proton conductivity, chemical and mechanical stabilities. However, the well-developed water channels in Nafion membrane have restricted its application in all vanadium redox flow batteries owing to the high permeation of vanadium ions and the cost. In this work, the water adsorption rate, resistivity and transference number of vanadium ions of sulfonated-graphene/Nafion composite membrane were investigated and compared with those of Nafion membrane in an effort to overcome the abovementioned drawbacks. It was found that the area resistivity and permeation rate of sulfonated-graphene/Nafion composite membrane were significantly reduced after the modification of Nation membrane by sulfonated grapheme. The results from the all vanadium redox flow battery indicated that the sulfonated-graphene/Nafion composite membrane exhibited better electrochemical performance, demonstrating potential application in all vanadium redox flow batteries.
