  "textContent": "A vanadium-chromium electrolyte, a method for preparing the same, and a redox flow battery composed thereof are provided. The vanadium-chromium electrolyte includes active substances and a free acid, the free acid acts as a proton conductive agent after ionization, and the active substances contain at least vanadium ions and chromium ions. The present disclosure further provides the method for preparing the vanadium-chromium electrolyte, which includes the following steps: dissolving a vanadium compound with a free acid, and obtaining a mixed solution of the free acid and vanadium ions through filtering; electrolytically reducing vanadium to an average valence state of 3.5 to 4 valence; adding a chromium compound, dissolving through stirring, and implementing a filtering; and adding pure water and an auxiliary reagent to adjust concentration, and preparing the vanadium-chromium electrolyte.",
