<p>By realizing or installing check valve liquid vein interrupters in each compartment of the battery the phenomenon of slow discharge of the retained volumes of electrolytes during long periods of inactivity of a redox flow battery, with the electrolyte pumps stopped altogether, can be practically eliminated with the effect that the battery is perfectly ready to deliver electric power immediately upon request even after prolonged periods of inactivity. Moreover, the presence of liquid vein interrupters on each compartment in either an outlet or an inlet port substantially preventing by-pass current during a not pumping phase, permits to increase the by pumping the electrolytes through the compartments of a battery stack intermittently, in other words in a pulsed manner, with a certain duty-cycle. Relatively brief pumping phases at relatively high flow rate alternated to phases of not pumping provide for a volumetrically adequate refreshing of the electrolytes present in the battery compartments and contrast the formation of gradients in the bodies of electrolyte.</p> |
