Among the flow batteries, the vanadium flow battery (VFB), which is put forward by Skyllas-Kazacos and co-workers [ 7, 8, 9 ], is one of the most promising choices as the same element (vanadium) is employed in both positive and negative sides, thus avoiding cross-contamination.
Increasing the flow rate improves the charge and discharge capacities of the battery, but this improvement tends to be smaller beyond a stoichiometric number of 9. This indicates that there is a saturation point close to λ = 9 beyond which no significant increase in capacity can be achieved.
