Abstract: A method is provided to enhance efficiency of carbon felts in a flow battery. The carbon felts are directly immersed in a mixed acid solution. The carbon felts with the solution are heated at a low temperature and processed through sonication. On surface defects of the carbon felts, —OH and C?O functional groups are efficiently generated. The functional groups catalyze the redox reaction of vanadium ions. More active positions are obtained on the carbon felts through the activation treatment. Both of valence exchange and redox velocity of the vanadium ions are enhanced. Thus, the present invention has simple and fast processes with easily regulated experimental parameters for good modification without high temperature treatment but low cost.
