New Liquid Cathodes for Lithium Batteries. Part A. Halocarbons.

摘要

Several halocarbons were selected for characterization as cathodes for lithium batteries after chemical stability testing with Li metal. Further testing comprised shock sensitivity with lithium, conductivity of halocarbon electrolytes, and the discharge behavior of assembled Li battery packs at 1ma/sq cm. Halocarbons were found to be much less shock sensitive with lithium than presently used sulfur oxychlorides. A literature search has revealed that they are also less toxic. The discharge capacity for 1,1,2,2-tetrachloroethane (2.8 AH/g carbon) exceeded that of thionyl chloride (2.2 AH/g carbon). These results show promise for the use of halocarbons in safer lithium batteries. (Author)
