Vanadium redox batteries have the unique advantage of using only one electrolyte, which dissolves V2O5 in H2SO4, to provide the potential redox reaction and the reversed reaction, allowing the battery to be circularly charged and discharged. This feature brings a wide range of applications, including the Wind Energy Market.
One disadvantage of vanadium redox-flow batteries is the low volumetric energy storage capacity, limited by the solubilities of the active species in the electrolyte. The cost of vanadium may be acceptable, because it is a relatively abundant material, which exists naturally in ~65 different minerals and fossil fuel deposits.
As vanadium is the active specie in both anolyte and catholyte, leakage of reactants from one electrolyte into the storage container of the other electrolyte will, in contrast to other flow batteries, not result in electrolyte contamination but only loss of energy storage capacity.
In terms of future outlook, we also provide practical guidelines for the further development of self-sustaining electrodes for vanadium redox flow batteries as an attractive energy storage system.
