LITHIUM-SILVER-CHLORIDE SECONDARY BATTERY INVESTIGATION.
Abstract
Aluminum cases for housing the lithium-silver chloridenonaqueous electrolyte cell system were prepared using an improved seal assembly technique. Propylene carbonate electrolyte conductivity may be increased by the addition of solvents such as ether and toluene. The electrodeposition of propylene lithium from 50 vol % solutions of these solvents with propylene carbonate LiCl and AlCl3 occurs at high efficiency. Silver chloride electrodes have been prepared by pasting a mix of 75% AgCl and 90% AgCl with 10% acetylene black. Cell heat measurements yield thermodynamic values for the postulated cell reaction of free energy, heat of reaction, and entropy which are within experimental accuracy equal to the theoretical values calculated for the following cell reaction with cell reactants and products in solid state: Li + AgCl yields LiCl + Ag. Lithium-silver chloride cell cycle life is improved at high temperature. A cell was constructed with electrodes sealed in a polyethylene case which had an energy density of 88 watt-hr/lb at 0.22 ma/sq cm current density.
