Title:
REDOX FLOW BATTERY
Document Type and Number:
WIPO Patent Application WO/2015/126131
Kind Code:
A1
Abstract:
The present invention relates to a redox flow battery and, more particularly, to a redox flow battery for supplying a battery cell with a catholyte and an anolyte and performing charging/discharging using a vanadium-containing active material and a cation exchange membrane, wherein the catholyte and the anolyte contain vanadium ions as active ions, a difference between the amount of the catholyte and the amount of the anolyte is maintained at 10% or less, and the total concentration of anions contained in the anolyte exceeds the total concentration of anions contained in the catholyte. Accordingly, the redox flow battery can control water transfer in the battery and minimize a change in the volumes of electrolytes.
