Battery storage systems become increasingly more important to fulfil large demands in peaks of energy consumption due to the increasing supply of intermittent renewable energy. The vanadium redox flow battery systems are attracting attention because of scalability and robustness of these systems make them highly promising.
In order to store electrical energy, vanadium species undergo chemical reactions to various oxidation states via reversible redox reactions (Eqs. (1) – (4)). The main constituent in the working medium of this battery is vanadium which is dissolved in a concentration range of 1–3 M in a 1–2 M H 2 SO 4 solution .
Among these batteries, the vanadium redox flow battery (VRFB) is considered to be an effective solution in stabilising the output power of intermittent RES and maintaining the reliability of power grids by large-scale, long-term energy storage capability .

Vanadium permeability Diffusion of the V ions from one half-cell to the other leads to discharge of the battery and, thus, determines the energy storage time of the battery. Extensive research has shown that the cationic membranes are susceptible to V permeability due to their attraction of the V species.
