The vanadium flow battery (VFB) can make a significant contribution to energy system transformation, as this type of battery is very well suited for stationary energy storage on an industrial scale (Arenas et al., 2017 ). The concept of the VFB allows conver electrical energy into chemical energy at high efficiencies.
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.
The membranes employed in vanadium flow batteries can be grouped into ion exchange membranes and physical separators; however, this topic will only focus on ion exchange membranes .
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.
Abstract: As a promising large-scale energy storage technology, all-vanadium redox flow battery has garnered considerable attention. However, the issue of capacity decay significantly hinders its further development, and thus the problem remains to be systematically sorted out and further explored.
