The ideal electrolyte for vanadium batteries needs to ensure the stability of high-concentration vanadium ions in different oxidation states over a wide temperature range. A key issue to be resolved is to improve the stability of V 5+ at high temperatures (50 °C) and V 3+ at low temperatures (−5 °C).
Their single vanadium element system avoids capacity fading caused by crossover contamination in iron-chromium flow batteries (ICFBs) . Additionally, VRFBs use an aqueous electrolyte, eliminating the safety risks associated with bromine vapor corrosion in zinc-bromine flow batteries (ZBFBs) .
