Abstract:
During the quarter a new cell fixture was placed in service to measure conductivities of liquid ammonia and solutions of salts in liquid ammonia. The cell fixture was used in different configurations for initial studies of voltaic cells having a pill type construction the conductivities of cell pills were also determined. Modification of the cell-fixture construction was accomplished to permit voltammetric studies in this environment. It was found that NH42SO4 is unsuitable as an insoluble acid catholyte when using m-dinitrobenzene as the active cathode material. It is believed that the rate of solution of the acid is too slow and that this is the cause of poor performance at high cursity. The study of cation effect showed that the zinc ion has a serious detrimental effect on cathode performance even when excess acid is present in the cell. For cells tested in the research single-cell test fixture, the thickness of the electrolyte pad was reduced to 13 mm without apparent degradation. A number of positive halogen compounds screened for use as cathodes in the ammonia system reacted violently with ammonia gas and with electrolyte solutions. Two of the eight compounds show slight promise.
