Vanadium Redox Flow Batteries (VRFBs) are proven technologies that are known to be durable and long lasting. They are the work horses and long-haul trucks of the battery world compared to the sports car, like fast Lithium-Ion (Li-Ion) batteries. However, VRFBs have developed a reputation for being notoriously expensive.
READ MOREKey takeaways. Flow batteries are unique in their design which pumps electrolytes stored in separate tanks into a power stack. Their main advantage compared to lithium-ion batteries is their longer lifespan, increased safety, and suitability for extended hours of operation. Their drawbacks include large upfront costs and low power density.
