Exposure of the polymeric membrane to the highly oxidative and acidic environment of the vanadium electrolyte can result in membrane deterioration. Furthermore, poor membrane selectivity towards vanadium permeability can lead to faster discharge times of the battery. These areas seek room for improvement to increase battery lifetime.
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.
