Abstract:

The report describes a project to develop a system capable of delivering energy in excess of 200 w-hrslb of total battery weight. Screening tests at the beginning of the program indicated that the lithiumcupric fluoride system offered the best possibility of success. Electrolyte studies indicated that the most promising solvents were propylene carbonate, dimethyl carbonate and dimethyl sulphite which in conjunction with lithium perchlorate yielded electrolytes having adequate conductance and which were inert towards the electrode materials. Anode studies revealed that lithium electrodes prepared from commercially available foil could be discharged over a wide range of current densities yielding high coulombic efficiency without appreciable polarization. The most encouraging techniques for cupric fluoride cathode fabrication were found to be a hot pressing method using polyethylene as a binder and a cold pressing method using paper floc as a binder. Multiplate assemblies were constructed containing nine electrodes and having a nominal capacity of 7 a.h. These were capable of being discharged in 1 F LiClO4propylene carbonate electrolyte at 2 masq. cm. 250 ma to yield 1 17 w-hrslb of total battery weight. Author
