The present invention describes an improved membrane for Redox Flow Batteries, in particular for Vanadium Redox Batteries and energy storage systems and applications employing the Vanadium Redox Cells and Batteries. Redox Flow Batteries involve the use of two redox couple electrolytes separated by an ion exchange membrane that is the most important cell component.

Perfluorinated membranes and improved electrolytes for redox cells and batteries

A vanadium halide redox cell including: a positive half cell containing a positive half cell solution including a halide electrolyte, a polyhalide complex, vanadium (IV) halide and vanadium (V) halide; a negative half cell containing a negative half cell solution including a halide electrolyte, vanadium (II) halide and vanadium (III) halide; wherein the ratio of the number of moles of polyhalide complex and vanadium (V):number of moles of vanadium (II) halide is about stoichiometrically balanced and wherein the ratio of the number of moles of polyhalide complex:the number of moles of vanadium (II) halide is in the range of from about 0.7:2 to about 1.3:2.
