This demonstrates the advantage that the flow batteries employing vanadium chemistry have a very long cycle life. Furthermore, electrochemical impedance spectroscopy analysis was conducted on two of the battery stacks. Some degradation was observed in one of the stacks reflected by the increased charge transfer resistance.

One big step! A new method to quantify electrolyte imbalance in vanadium redox flow batteries is proposed. The key principle is a correlation between the duration of the potential plateaus in the open-circuit voltage during initial charging and the amount of vanadium ions of a certain oxidation state in the half-cell electrolytes.
One more advantage of these batteries – the acidity levels are much lower than lead-acid batteries. In its lifespan, one StorEn vanadium flow battery avoids the disposal, processing, and landfill of eight lead-acid batteries or four lithium-ion batteries.
