Vanadium redox flow batteries (VRFBs) have emerged as a leading solution, distinguished by their use of redox reactions involving vanadium ions in electrolytes stored separately and circulated through a cell stack during operation. This design decouples power and energy, allowing flexible scalability for various applications.
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) .
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).
Additionally, a higher mass flow rate can improve the utilization of vanadium ions, further contributing to the observed increase in VRFB capacity as the stoichiometric number rises. This relationship highlights the significance of optimizing both stoichiometric factors and flow dynamics to enhance the performance of vanadium flow batteries.
