HIGH ENERGY SYSTEM (ORGANIC ELECTROLYTE).

The results of previous studies of the LiCuF2 couple indicated that the major problems remaining to be solved were in improving the activated storage and discharge rate capabilities. The major efforts in the present investigations concerned with attempts to alleviate the above-mentioned problems. In the case of activated storage limitations, it was thought that certain impurities in the electrolyte components might promote dissolution of CuF2. Both LiClO4 and propylene carbonate were submitted to extensive purification procedures. In addition, LiClO4 was specially treated to remove traces of water. New solvents and solvent mixtures were evaluated in an effort to develop an improved electrolyte. New conductive additives were evaluated in order to determine their effect on the discharge efficiency and activated storage capability of the CuF2 cell was evaluated under both vacuum and dry argon storage conditions. A voltammetric technique, using a mercury pool cell was employed to determine the constitution of the soluble copper species in organic electrolyte.
