Recent development of sodium polysulfide/bromide redox flow battery and vanadium ion redox flow battery

Much research focuses on redox flow batteries in recent years.Sodium polysulfide/bromide redox flow battery(PSB) and vanadium ion redox flow battery(VRB) are taking the leading role in redox flow batteries.Development,composition and properties of PSB and VRB,as well as their applications were discussed and evaluated.Their advantage/disadvantage and application field were also compared.In addition,the developing trend of redox flow batteries was reviewed.
