Traditionally, much of the global vanadium supply has been used to strengthen metal alloys such as steel. Because this vanadium application is still the leading driver for its production, it’s possible that flow battery suppliers will also have to compete with metal alloy production to secure vanadium supply.
In this work the behaviour of the vanadium redox flow battery is examined under a variety of short-circuit conditions (e.g. with and without the pumps stopping as a result of the short). In contrast to other battery types, only a small proportion of the electroactive material, in a flow battery, is held between the electrodes at any given time.
Vanadium makes up a significantly higher percentage of the overall system cost compared with any single metal in other battery technologies and in addition to large fluctuations in price historically, its supply chain is less developed and can be more constrained than that of materials used in other battery technologies.
