The effect of the counter ion for Vanadium Redox Flow Batteries

We have published an open access article about the effect of the counter ion in the electrolyte of Vanadium Redox Flow Batteries (VRFB). Sulphate and pure chloride based electrolytes have been compared regarding its electrochemical properties in half-cells and batteries. We show here that the usage of pure chloride based electrolyts results in lower performance and a reaction of V(V) with chlorine.
