Customer ServiceOperating Principle of a Vanadium Redox Flow Battery (VRFB) The VRFB consist of positive and negative electrodes and an ion exchange membrane. The electrolytes with the vanadium ions are stored in two tanks and they are recirculated through the set of cells (also known as stack) by mechanical pumps, see Figure 4.
One disadvantage of vanadium redox-flow batteries is the low volumetric energy storage capacity, limited by the solubilities of the active species in the electrolyte. The cost of vanadium may be acceptable, because it is a relatively abundant material, which exists naturally in ~65 different minerals and fossil fuel deposits.
Vanadium redox flow batteries (VRFBs) have been highlighted for use in energy storage systems. In spite of the many studies on the redox reaction of vanadium ions, the mechanisms for positive and negative electrode reaction are under debate.
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.
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.
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.
