Zinc–bromine battery

SummaryTypesOverviewFeaturesElectrochemistryApplicationsHistoryFurther readingThe zinc–bromine flow battery (ZBRFB) is a hybrid flow battery. A solution of zinc bromide is stored in two tanks. When the battery is charged or discharged, the solutions (electrolytes) are pumped through a reactor stack from one tank to the other. One tank is used to store the electrolyte for positive electrode reactions, and the other stores the negative. Energy densities range between 60 and 85 W·h/kg. The aqueous electrolyte is composed of zinc bromide salt dissolved in water. During charge, metallic zi
