One of the major costs in vanadium redox flow batteries is the ion-permeable membrane used to minimize so-called crossover. This phenomenon, which can cause capacity losses that can reach up to 50%, occurs during charging and recharging, when battery electrolyte components cross the membrane in the battery cell and the redoxmers which are redox-active molecules that can store energy in the batteries' electrolytes migrate to the wrong side of the device. This, in turn, means that cell and stack balancing is not required. Extensive research efforts have been reported to remove the membrane from the cell, but most of them were applicable in small lab-scale cell due to the intrinsic issue of intermix of reactants from both sides of the cell, requiring in-depth research to resolve the intermixing problem. 2019 Nov;31(46):e1904690. 42.0% over 20 cycles, respectively.
