In general, the molar flux of vanadium in one direction is greater than in the other, i.e., the crossover is asymmetric, thus leading to a build-up in one side and a depletion in the other. This results in a condition known as stoichiometric imbalance that reduces the battery capacity but can be recovered by a simple remix of the electrolytes [22].
