Fact Sheet: Vanadium Redox Flow Batteries (October 2012)
Compared to pure sulfuric acid, the new solution can hold more than 70% more vanadium ions, increasing energy storage capacity by more than 70%. The use of Cl- in the new solution also

These electrolyte solutions were investigated in terms of performance in vanadium redox flow battery (VRFB).
Flow batteries always use two different chemical components into two tanks providing reduction-oxidation reaction to generate flow of electrical current.
In a typical VRFB, vanadyl sulfate (VOSO 4) is dissolved in sulfuric acid (H 2 SO 4) and water to form the electrolyte.
Vanadium redox flow batteries (VRFBs) are promising candidates for large-scale energy storage, and the electrolyte plays a critical role in
