[0002] An all-vanadium flow battery is a redox battery with vanadium as the active material in a circulating liquid state. The electrical energy in a vanadium battery is stored as chemical energy in a sulfuric acid electrolyte containing vanadium ions of varying valences. The electrolyte is pumped into the battery stack via an external pump and mechanically forced to circulate through a closed loop of different storage tanks and half-cells. Using a proton exchange membrane as the separator of the battery pack, the electrolyte solution flows parallel to the electrode surfaces, generating an electrochemical reaction. The current is collected and conducted by dual electrode plates, converting the chemical energy stored in the solution into electrical energy.
