The longevity of flow batteries makes them ideal for large-scale applications where long-term reliability is essential. Safety: Flow batteries are non-flammable and much safer than lithium-ion batteries, which can catch fire under certain conditions, such as overcharging or physical damage.
Scalability: One of the standout features of flow batteries is their inherent scalability. The energy storage capacity of a flow battery can be easily increased by adding larger tanks to store more electrolyte.
Flow batteries have a storied history that dates back to the 1970s when researchers began experimenting with liquid-based energy storage solutions. The development of the Vanadium Redox Flow Battery (VRFB) by Australian scientists marked a significant milestone, laying the foundation for much of the current technology in use today.
Safety: Flow batteries are non-flammable and much safer than lithium-ion batteries, which can catch fire under certain conditions, such as overcharging or physical damage. Since the electrolytes in flow batteries are aqueous solutions, they do not pose the same risk of thermal runaway or explosion.
Vanadium flow batteries from Invinity are among the safest storage technologies on the grid today. The fundamental stability of their underlying vanadium technology gives them dramatically lower risk of fires and fire-related injuries. Independent testing to the UL9540A standard has shown that they have no risk of thermal runaway.
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 .
