Abstract

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.
