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 Vto a first electrode and a second electrode of at least one cell of a flow battery. The vanadium Vat the first electrode is converted to vanadium Vand the vanadium Vat the second electrode is converted to vanadium Vby providing electrical energy to the electrodes. A reducing agent is then provided to the vanadium Vat the second electrode to reduce the Vto vanadium V. The vanadium Vat the first electrode is then converted to vanadium Vand the vanadium Vat the second electrode is then converted to vanadium Vby providing electrical energy to the electrodes. A simple method to produce predominantly vanadium Velectrolyte from a Vsource, such as VO, is also taught.
