Abstract: A method of in-situ electrolyte preparation in a flow battery includes providing a vanadium-based electrolyte solution having vanadium ions of predominantly vanadium V4+ to a first electrode and a second electrode of at least one cell of a flow battery. The vanadium V4+ at the first electrode is converted to vanadium V3+ and the vanadium V4+ at the second electrode is converted to vanadium V5+ by providing electrical energy to the electrodes. A reducing agent is then provided to the vanadium V5+ at the second electrode to reduce the V5+ to vanadium V4+. The vanadium V3+ at the first electrode is then converted to vanadium V2+ and the vanadium V4+ at the second electrode is then converted to vanadium V5+ by providing electrical energy to the electrodes. A simple method to produce predominantly vanadium V4+ electrolyte from a V5+ source, such as V2O5, is also taught.
