Vanadium Redox Flow Batteries (VRFBs) have emerged as a promising solution for energy storage, offering numerous advantages over traditional battery technologies. With the increasing demand for renewable energy sources and the need for efficient energy storage systems, VRFBs have gained significant attention in recent years. In this article, we will explore the basics of VRFBs and understand why they are considered a game changer for energy storage.
At the heart of a VRFB is a redox reaction involving vanadium ions in different oxidation states. Unlike conventional batteries, VRFBs store energy in a liquid electrolyte containing vanadium ions. The two electrolyte solutions, one with vanadium in its higher oxidation state (V5+) and the other with vanadium in its lower oxidation state (V2+), are separated by a membrane. During charging and discharging, the vanadium ions undergo a reversible redox reaction, allowing the battery to store and release electrical energy.
Ferro-Alloy Resources Ltd (LON:FAR) is developing the giant Balasausqandiq vanadium deposit in Kyzylordinskaya oblast of southern Kazakhstan. The ore at this deposit is unlike that of nearly all other primary vanadium deposits and is capable of being treated by a much lower cost process.
