CHEMOELECTRIC ENERGY CONVERSION FOR NONAQUEOUS RESERVE BATTERY SYSTEMS.
NAVAL ORDNANCE LAB CORONA CALIF
Experimental cell studies in the ionic melt system MgKSCN-NaSCN-kaolinUO3-electrolyte-CNi were completed. New studies, which include electrical conductivity, polarography, and chronopotentiometry, were begun on electrolytes with dimethyl sulfone solvent m.p. 109C. Electrode reaction studies of nitrobenzene in neutral liquid ammonia electrolytes indicate the formation of a phenyl NO2 negative radical with a half-life of approximately half an hour, which can be expected to influence short-life battery discharge performance. Liquid ammonia hardware cells with Mg metadinitrobenzene mDNB electrodes 1 sq cm in area were tested at 25C. The best performance was obtained from MgKSCNNH4SCN-mDNB-CAg cells at 25C, which averaged 2.12 volts peak, with a 10 drop during a 5-min discharge into a constant 100-ohm load 21 masq cm peak cursity.
