HIGH ENERGY SYSTEM (ORGANIC ELECTROLYTE)
Abstract
Progress is described of work undertaken to improve the activated storage life, and to increase the current density capability of the Li/CuF2 cells. A continuing search was made for new electrolyte solvents in order to obtain an electrolyte with properties superior to those of LiClO4/propylene carbonate solutions. Tetramethylurea and 1,2-propylene glycol sulfite were investigated, and the organic sulfur compound was found to be promising. Methods for purifying graphite were investigated as a result of the observations that certain impurities were adversely affecting cathode performance on activated stand. Complexones were re-evaluated, and although it was found that ethylene diamine effected an improved activated stand for Li/CuF2 cells, the improvement was only marginal. Studies of CuF2 cathode discharge kinetics were continued and, it appears from the results obtained using chronopotentiometric techniques that the reaction is diffusion controlled in LiClO4/propylene carbonate solutions.
