The manufacturing facility, with a production capacity of up to 33 MWh of VFB energy storage annually, is the centrepiece of AVL''s complete ''pit to battery'' strategy that aims to provide a full-cycle vanadium supply chain from mining to battery production. The vanadium pentoxide used for electrolyte manufacture will initially be sourced
Unlike technologies that rely on different elements to make up the positive and negative sides of the battery, vanadium''s ability to exist in different oxidation states allows VFBs to use that metal as both the positive and negative "couple" inside the battery cell. This eliminates many of the common modes by which traditional battery chemistries become contaminated and degrade
As mentioned previously, cross contamination largely affects the overall performance of the flow battery, as the vanadium crossover will react with the opposing vanadium species and will require regeneration [84]. In order to address the above considerations, numerous membranes have been developed. The two most common applied membranes are

Vanadium redox flow battery (VRFB) technology is a leading energy storage option. Although lithium-ion (Li-ion) still leads the industry in deployed capacity, VRFBs offer new capabilities that enable a new wave of industry growth. Flow batteries are durable and have a long lifespan, low operating costs, safe
For commercial vanadium electrolytes, the vanadium concentration is in the range of 1.5∼1.8 M . When the vanadium concentration is greater than 1.5 M, the acid concentration in the electrolyte needs to be accurately controlled at 3 M, and the operating temperature is between 10 and 40 °C.
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.
Vanadium flow batteries show technical promise for decarbonizing the power sector. High and volatile vanadium prices limit deployment of vanadium flow batteries. Vanadium is globally abundant but in low grades, hindering economic extraction. Vanadium's supply is highly concentrated as co-/by-product production.
While the battery architecture can host many different redox chemistries, the vanadium RFB (VRFB) represents the current state-of-the-art due to its favorable combination of performance and longevity. However, the relatively high and volatile price of vanadium has hindered VRFB financing and deployment opportunities.
