Bellows, R J; Kantner, E

This patent describes an electrochemical cell having a metal bromine couple. The cell consists of: an electrode structure on which the metal of the couple is deposited during charging of the cells; the counterelectrode structure at which cathodic bromine is generated during charging of the cell; an aqueous electrolyte comprising an aqueous metal bromide solution, the metal being the same as the metal of the metal bromine couple, the aqueous electrolyte containing a water soluble complexing agent capable of forming a water immiscible complex with cathodic bromine; and a microporous separator between the electrode and the counterelectrode structure, the microporous separator being selected from separators which are preferentially wet by aqueous electrolyte and are not wet by the water immiscible complex of cathodic bromine.
