But why? I thought one of the chief advantages of flow batteries was a lower cost per kWh at scale, as the expensive electrodes can be sized for peak power, while the cheaper electrolyte can be sized for capacity. Perhaps the economies of scale in lithium-ion batteries have had a bigger impact on cost than this clever split, so lion is actually cheaper per kwh?
