Vanadium: The Energy Metal - Visual Capitalist

Oct 05, 2017· Vanadium redox flow batteries (VRFBs) are fairly unique in the battery world. They work by taking advantage of the natural properties of vanadium, a metal with four different oxidation states. But rather than using the metal in a solid state, vanadium electrolyte (a liquid solution) is used for both half-cells and the configuration is divided ...
