Abstract
Official abstract text for this publication.
The present disclosure relate to a method for operating a redox flow battery, which includes the steps of discharging the redox flow battery having an anode electrolyte and a cathode electrolyte when a volume difference between the anode electrolyte and the cathode electrolyte is within 20% of a total volume of the anode electrolyte and the cathode electrolyte, while maintaining an open circuit voltage of lower than 1.3 V/cell, and moving the anode electrolyte and/or the cathode electrolyte so that the volume difference is 2% or less between the anode electrolyte and the cathode electrolyte in the redox flow battery after the discharging.
First claim
Opening claim text (preview).
1 . A method for operating a redox flow battery, the method comprising the steps of: discharging the redox flow battery having an anode electrolyte and a cathode electrolyte when a volume difference between the anode electrolyte and the cathode electrolyte is within 20% of a total volume of the anode electrolyte and the cathode electrolyte, while maintaining an open circuit voltage of lower than 1.3 V/cell; and moving the anode electrolyte and/or the cathode electrolyte so that the volume difference is 2% or less between the anode electrolyte and the cathode electrolyte in the redox flow battery after the discharging. 2 . The method for operating a redox flow battery according to claim 1 , further comprising charging the redox flow battery after the moving of the anode electrolyte and/or the cathode electrolyte. 3 . The method for operating a redox flow battery according to claim 1 , wherein the discharging comprises overdischarging the redox flow battery under conditions of a constant current or a constant voltage. 4 . The method for operating a redox flow battery according to claim 1 , wherein the discharging comprises discharging the redox flow battery until the open circuit voltage becomes 0.6 to 0.8 V/cell. 5 . The method for operating a redox flow battery according to claim 4 , wherein the discharging of the redox flow battery until the open circuit voltage becomes 0.6 to 0.8 V/cell precedes the moving of the anode electrolyte and/or the cathode electrolyte so that the volume difference is 2% or less. 6 . The method for operating a redox flow battery according to claim 1 , wherein the redox flow battery is a vanadium redox battery, a polysulfide bromide redox flow battery, or a zinc-bromine redox flow battery.
