Corrosion behavior of a positive graphite electrode in vanadium redox flow battery

The overpotential for gas evolution on positive graphite electrode decreases due to the functional groups of COOH and C O introduced on the surface of graphite electrode during corrosion process, which can self-catalyze the oxidation of carbon atoms therefore, accelerates corrosion process.
