METALL-BROM-ZELLE MIT ADDITIV ENTHALTENDEN ELEKTROLYTEN.

摘要

The cell includes an electrode structure (19) on which to deposit the metal, for example zinc, of the couple and a counterelectrode (17) at which to generate bromine. A microporous membrane (18) separates the electrode and counterelectrode. The cell further includes an aqueous electrolyte comprising an aqueous metal bromide solution containing a water soluble bromine complexing agent capable of forming a water immiscible complex with bromine. The aqueous electrolyte contains an additive capable of decreasing the wettability of the microporous separators employed in such cells by such water immiscible bromine complexes. Preferred such additives are sodium dodecyl sulfate and sodium dodecylbenzene sulfonate.
