Various embodiments include a method for operating an electrically rechargeable redox flow battery comprising: using a redox flow battery having a first chamber and a second chamber separated by a membrane, wherein the first chamber comprises a cathode and the second chamber comprises an anode; conducting a first electrolyte as catholyte into the first chamber and conducting a second electrolyte as anolyte into the second chamber; and charging or discharging the redox flow battery. The first electrolyte comprises a first reduction-oxidation pair and the second electrolyte comprises a second reduction-oxidation pair. At least one of the first electrolyte and the second electrolyte comprises a pH-stabilizing buffer for chemically stabilizing the reduction-oxidation pair.

Redox flow battery and method for operating a redox flow battery

Various embodiments include an electrically rechargeable redox flow battery comprising: a first chamber; a second chamber; a membrane separating the first chamber from the second chamber; a cathode in the first chamber; and an anode in the second chamber. At least one of the cathode and the anode comprises a first planar surface including elevations enlarging the surface area. The elevations form flow channels for an electrolyte. The at least one of the cathode and the anode further comprises a material selected from the group consisting of: lead, bismuth, zinc, titanium, molybdenum, and tungsten.
