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.

One such promising battery employs the chemistry of zinc and bromine [29], thus has higher energy density (especially due to zinc) than a battery based on vanadium. It is a so called hybrid system, which differs from the conventional flow batteries in that at least one of the redox pair is not fully soluble and it can be a metal or gas.
