A novel cathodic electrolyte based on H2C2O4 for a stable vanadium redox flow battery with high charge–discharge capacities

For the first time, a novel V(IV)/V(V) electrolyte based on H2C2O4 was developed for a stable vanadium redox flow battery, which exhibits significantly improved redox reversibility and reaction kinetics with carbon-based electrodes, and impressive charge–discharge capacities.
