Vanadium Redox Flow Battery. Vanadium is a hard, malleable transition metal more commonly known for its steel-making qualities. Redox, which is short for reduction oxidation, utilises a vanadium ion solution that can exist in four different oxidation states to store energy. This creates one electroactive element, enabling the current circulation.
