The present invention provides a redox flow battery that can suppress generation of deposits on a positive electrode. A redox flow battery that charges/discharges by supplying a positive-electrode electrolyte solution and a negative-electrode electrolyte solution to a battery cell that is provided with a positive electrode, a negative electrode, and a diaphragm interposed between the electrodes. The positive-electrode electrolyte solution contains manganese ions and additional metal ions, and the negative-electrode electrolyte solution contains at least one type of metal ion selected from among titanium ions, vanadium ions, chromium ions, and zinc ions. The additional metal ions contained in the positive-electrode electrolyte solution are at least one type from among aluminum ions, cadmium ions, indium ions, tin ions, antimony ions, iridium ions, gold ions, lead ions, bismuth ions, and magnesium ions. |
