Vanadium Redox Flow Batteries (VRFBs) work with vanadium ions that change their charge states to store or release energy, keeping this energy in a liquid form. Lithium-Ion Batteries pack their energy in solid lithium, with the energy dance happening as lithium ions move between two ends (electrodes) when charging or using the battery.
In a charging operation, on the positive side, tetravalent vanadium ions oxidize to pentavalent ions, with the release of H + ions and electrons, while on the negative side there is a reduction of trivalent ions to bivalent ions, as react with electrons that arrive through of the external circuit [31].Their coloring identifies these different vanadium ions …
