OverviewHybridHistoryDesignEvaluationTraditional flow batteriesOrganicOther types

The hybrid flow battery (HFB) uses one or more electroactive components deposited as a solid layer. The major disadvantage is that this reduces decoupled energy and power. The cell contains one battery electrode and one fuel cell electrode. This type is limited in energy by the electrode surface area. HFBs include zinc–bromine, zinc–cerium, soluble lead–acid, and all-iron flow batteries. Weng et al…
