Title
(EN) REDOX FLOW BATTERY SYSTEM AND METHOD OF OPERATING REDOX FLOW BATTERY
Abstract
(EN)

A redox flow battery system including: a positive-electrode electrolyte tank (11) in which a positive-electrode electrolyte containing tetravalent and/or pentavalent vanadium is stored; a positive-electrode electrolyte outgoing pipe (13) and positive-electrode electrolyte return pipe (14) for circulating the positive-electrode electrolyte between the positive-electrode electrolyte tank and a battery cell (2); a negative-electrode electrolyte tank (21) in which a negative-electrode electrolyte containing divalent and/or trivalent vanadium is stored; a negative-electrode electrolyte outgoing pipe (23) and a negative-electrode electrolyte return pipe (24) for circulating the negative-electrode electrolyte between the negative-electrode electrolyte tank (21) and the battery cell; a maintenance tank (40) in which a cleaning liquid containing sulfuric acid is stored; and a cleaning liquid outgoing pipe (41) and a cleaning liquid return pipe (42) for circulating the cleaning liquid between the maintenance tank (40) and the battery cell. Also disclosed is a method for operating the redox flow battery.
