Abstract: Disclosed are: a redox flow battery (RF battery) that can minimize the precipitation of precipitates while still producing a high emf; and a method for running a redox flow battery. The disclosed RF battery (100) charges and discharges a battery cell by supplying a positive-electrode electrolyte solution and a negative-electrode electrolyte solution thereto. Said battery cell is provided with a positive electrode (104), a negative electrode (105), and a barrier membrane (101) interposed between the electrodes (104 and 105). The positive-electrode electrolyte solution contains either manganese ions or both manganese ions and titanium ions. The negative-electrode electrolyte solution contains at least one of the following metal ions: titanium ions, vanadium ions, chromium ions, zinc ions, and lead ions. By including titanium ions in the positive-electrode electrolyte solution and running the RF battery (100) such that the charging depth of the positive-electrode electrolyte solution is at most 90%, the precipitation of precipitates such as MnO

Abstract: The present invention provides method of producing a trivalent and tetravalent mixed vanadium compound having excellent solubility with sulfuric acid directly from a tetravalent or pentavalent vanadium compound by using a reducing agent,and a method of producing a vanadium electrolyte. For example, a vanadium compound mainly containing a pentavalent vanadium compound; sulfur and concentrated sulfuric acid in molar ratios with respect to (one mol of vanadium atom in the pentavalent vanadium compound) 0.35 to 0.4:1.2 to 1.9 are kneaded into paste form, and the paste-form mixture is calcined at a temperature of not less than 150° C. to less than 440° C. so that a trivalent and tetravalent mixed vanadium compound is obtained, and a redox flow battery-use vanadium electrolyte is obtained by dissolving the trivalent and tetravalent mixed vanadium compound in a sulfuric acid solution.
