1、Vanadium Redox FlowEnergy Storage Technology Presentation2024 Challenge:Integrating weather-dependent production into the system.solution:ENERGY STORAGE WITH VRFB(Vanadium Redox Flow Battery)TECHNOLOGYThe vanadium redox flow battery operates based on the reduction and oxidation of vanadium in differ

2、ent ionized states.Vanadium is an easily accessible material,found naturally and recoverable from various waste streams.The tanks contain electrolytes,which are liquids capable of conducting electricity.One tank holds positively charged vanadium ions(V5+),while the other contains an electrolyte fill

3、ed with V2+.The vanadium battery is a type of flow battery,meaning it generates electricity by pumping liquid from external tanks into a central battery tank where the liquids mix.Pumps in the containers move the electrolyte filled with ions from both tanks to a third tank.Here,a chemical reaction c
