ABSTRACT:
An improved aqueous metal-halogen electrochemical cell, particularly a zinc bromide cell, contains a water soluble tetraorgano-substituted ammonium salt in the electrolyte which forms a substantially water insoluble liquid complex with cathodic halogen thereby reducing self-discharge of the cell. Particularly preferred as the ammonium salt is N-ethyl, N-methyl morpholinium bromide.
