Vanadium redox flow batteries (VRFBs) can effectively solve the intermittent renewable energy issues and gradually become the most attractive candidate for large-scale stationary energy storage. However, their low energy density and high cost still bring challenges to the widespread use of VRFBs.
Interest in the advancement of energy storage methods have risen as energy production trends toward renewable energy sources. Vanadium redox flow batteries (VRFB) are one of the emerging energy storage techniques being developed with the purpose of effectively storing renewable energy.
In order to store electrical energy, vanadium species undergo chemical reactions to various oxidation states via reversible redox reactions (Eqs. (1) – (4)). The main constituent in the working medium of this battery is vanadium which is dissolved in a concentration range of 1–3 M in a 1–2 M H 2 SO 4 solution .
The proposed model is based on a 1 kW/1 kWh VRFB system described in . On the electrochemical side, vanadium redox batteries work based on the oxidation and reduction of vanadium species, whose chemical reactions are given as follows.
