Safety is becoming more important for companies deploying large batteries. The intrinsic non-flammability of the water-based chemistry of vanadium redox flow batteries makes them ideal for this growing trend, especially in densely populated areas where the safety risk from fire and smoke is greatest.
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.
The vanadium redox flow battery (VRFB) has gone from being a laboratory curiosity, to gaining significant commercial application over the last decades . To date over a hundred systems have been installed worldwide, for stationary energy supply. Redox flow batteries store energy chemically in positive and negative electrolytes.
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.
This is one of the reasons for suggesting that redox flow batteries are safe Battery safety is an important and topical issue. Many thousands of articles published on lithium-based batteries have considered some aspect of safety. In contrast very little has been reported on electrical safety of the VRFB, or other types of flow battery .
