Polymer Electrolyte Membranes for Vanadium Redox Flow …
During the actual operation of a flow battery, the active species may inevitably transport through the membrane, which is also known as the vanadium-ion crossover phenomenon. Such process leads to imbalance of electrolyte volume and concentration, and further result to capacity loss, which is also known as the self-discharge.
