Metal halogen electrochemical cell. [Zn or Cd/Br/sub 2/]

Patent ·
OSTI ID:5240949
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, and thereby reduces self-discharge of the cell. Particularly preferred as the ammonium salt is N-ethyl, N-methyl morpholinium bromide. 1 figure, 6 tables.
