摘要： The present invention provides a redox flow type battery which a liquid-circulating battery comprising a battery cell and storage tanks for positive and negative electrolytes, wherein the battery cell is separated by a membrane to provide a positive cell and a negative cell, each cell having a liquid-permeable porous electrode disposed therein, wherein the positive and negative electrolytes are sulfuric acid aqueous solutions with vanadium ion concentrations of 0.5 mol/l to 8 mol/l and the electrolyte which migrates through the membrane over cycles of charge and discharge is returned from the storage tank where the liquid increases to the storage tank where the liquid decreases in order to keep the change in the amounts of the positive and negative electrolytes in a certain range while charge and discharge are carried out.
