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.
