摘要： A vanadium redox flow battery employs a single electrolyte as a starting material to be placed in equal amounts in the positive and negative electrolyte storage tanks for supporting electrolytes containing zinc and chloride ions. A supporting solution includes chloride ions and zinc ions, and a half-cell solution including vanadium ions based on an aggregate oxidation state around +3.5 is disposed in the supporting solution to form the electrolyte solution for the redox flow battery. With HCl as a supporting electrolyte, as an alternative to conventional sulfuric acid, the use of zinc provides multiple benefits in the preparation of vanadium-based electrolytes.
