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.
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.
This review on the various approaches to prepare polymeric membranes for the application in Vanadium Redox Flow Batteries (VRB) reveals various factors which should be considered when developing new membranes materials with or without the addition of non-polymeric materials.
Also, the electrolyte utilization increases from 54.1% to 68.4%, even at a high current density of 240 mA•cm−2 . Moreover, the durability of the hybrid VANADion membrane in multiple charge/discharge cycling was shown to be similar to that of Nafion 115 and VANADion over the 80–240 mA•cm −2 current density range .
However, they suffer from the cross-mixing of vanadium ions. The membrane has the important task to transfer the charge balancing species between the half cells, at the same time to be selective enough to separate Vanadium species, where their mixing leads to auto battery discharge [75, 113].
In this way a cationic charged layer can formed on the surface of Nafion which is strongly bonded to the Nafion surface. As a result of the repulsive layer the membrane showed a lower vanadium ion crossover rate, at the cost of a higher area resistance.
