AbstractBy coupling the advantages of the vanadium redox flow battery and the acid/alkaline hybrid battery concepts, a novel Vanadium-metal hydride (V-MH) hybrid rechargeable flow battery is developed. The V-MH flow battery consists of graphite felt positive electrode in flowing VOSO4-H2SO4 electrolyte and metal hydride negative electrode in flowing KOH, the two flowing streams are separated by a bipolar membrane. Hybridizing the V4+/V5+ coupled with metal hydride eliminates the problem of V2+ oxidation as in VRF battery. In the meantime, the higher voltage and higher capacity achieved is a result of the extra energy store/released in acid-alkaline neutralization corresponding to =-79.85 kJ/mol. The charge and discharge electrode reactions in this acid/alkaline Vanadium-Metal Hydride flow system are as follows ...
