Vanadium Redox Flow Battery
The raw material cost of vanadium has previously been estimated to contribute $140/kWh to the battery cost, which corresponds to approximately 20 % of the total investment costs for a VRB

Samantha McGahan of Australian Vanadium writes about the liquid electrolyte which is the single most important material for making vanadium flow batteries, a leading contender for providing several hours of storage, cost-effectively. Vanadium redox flow batteries (VRFBs) provide long-duration energy storage.
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.
