Energy storage is a solution to the problem of renewable energy intermittency. The vanadium redox flow battery (VRFB) is one such energy storage technology, allowing energy to be stored electrochemically in vanadium electrolytes until required. The advantages of VRFBs include independently scalable energy and power characteristics, high reliability and long life time. The broad aim of this work was to investigate the main problems VRFBs currently present: 1. temperature stability of the vanadium electrolyte, and 2. chemical stability and vanadium cation permeability issues of the ion permeable separator membrane. It was determined that the concentrations of vanadium and sulfuric acid in the electrolyte have a greater impact on thermal stability than the presence of additives. Decreasing the sulfuric acid concentration, improves cold temperature stability of the vanadium electrolyte without impeding stability at elevated temperature.
