Lithium Anode Limited Cycle Battery Investigation
Abstract
This investigation of the lithium-cupric fluoride and lithium-cobaltic trifluoride electrochemical systems has as its goal the development of technology sufficient to build 1500 a-hr batteries with high (300 whr/lb) energy to weight figures. Selected glass fiber filter paper appears to have suitable characteristics of resistance, absorption and retention to be useful in these batteries. Polarographic and cell tests of cobaltic trifluoride cathodes indicate that the major electrical energy producing reaction is probably that of cobaltous ion to cobalt metal. The cobaltic ion reacts with cobalt metal to form the cobaltous ion. These reactions result in a plateau of about 2.7 watts rather than the theoretical 3.5 volts. The cupric fluoride cathode appears at this time to be reduced to copper metal without intermediate voltage plateau. The problems associated with the cupric fluoride cathode are those of obtaining a proper electrode matrix for efficient electrochemical reduction.
