OverviewHistoryAdvantages and disadvantagesMaterialsOperationSpecific energy and energy densityApplicationsCompanies funding or developing vanadium redox batteriesThe vanadium redox battery (VRB), also known as the vanadium flow battery (VFB) or vanadium redox flow battery (VRFB), is a type of rechargeable flow battery. It employs vanadium ions as charge carriers. The battery uses vanadium''s ability to exist in a solution in four different oxidation states to make a battery with a single electroactive element instead of two. For several reasons
