HIGH-ENERGY BATTERY SYSTEM STUDY.
Abstract
The behavior of high-energy cathode systems in lithium bromide-propylene carbonate electrolyte was investigated by galvanostatic polarization curves and prolonged discharge tests. An effort was made to promote the reduction of silver (II) oxide in the organic medium by means of additives that could act as receivers for the oxide ion. Water at concentrations of up to 10 percent was not effective for this purpose. Three solid oxygen receivers, K2S2O7, Na2S2O5, and Na4P2O7, did not improve the cathodic behavior of silver oxide. Other cathode materials investigated were cupric iodate, potassium persulfate, cupric fluoride, and (as a comparison system) silver chloride. The iodate and persulfate were inactive in the propylene carbonate electrolyte, but apparent utilization efficiencies of 31 and 70 percent were achieved for the reduction of cupric fluoride and silver chloride, respectively.
