Vanadium redox flow batteries (VRFBs) represent a revolutionary step forward in energy storage technology. Offering unmatched durability, scalability, and safety, these batteries are a key solution for renewable energy integration and long-duration energy storage. VRFBs are a type of rechargeable battery that stores energy in liquid electrolytes.
All-vanadium flow batteries have been demonstrated at 100 MW/400 MWh scale by researchers at DICP. However, the vanadium electrolytes in these flow batteries are expensive and toxic.
A vanadium / cerium flow battery has also been proposed . VRBs achieve a specific energy of about 20 Wh/kg (72 kJ/kg) of electrolyte. Precipitation inhibitors can increase the density to about 35 Wh/kg (126 kJ/kg), with higher densities possible by controlling the electrolyte temperature.
Other useful properties of vanadium flow batteries are their fast response to changing loads and their overload capacities. They can achieve a response time of under half a millisecond for a 100% load change, and allow overloads of as much as 400% for 10 seconds. Response time is limited mostly by the electrical equipment.
Currently, commercial vanadium electrolytes are primarily H 2 SO 4 (2.5–3.5 mol/L) solutions dissolving 1.5–2 mol/L vanadium, with energy densities typically around 25 Wh/L, significantly lower than Zn mixed flow batteries, which can achieve energy densities up to 70 Wh/L [10, 20].
The battery uses vanadium's ability to exist in a solution in four different oxidation states to make a battery with a single electroactive element instead of two. For several reasons, including their relative bulkiness, vanadium batteries are typically used for grid energy storage, i.e., attached to power plants/electrical grids.
