LITHIUM-NICKEL HALIDE SECONDARY BATTERY INVESTIGATION

Abstract

Two methods of protecting the tabs of the NiCl2 electrode from corrosion by chlorine have been developed. The first is a protective coating and the second is the use of Monel 400 alloy instead of nickel. These methods have also shown to be satisfactory for the nickel fluoride system. The Monel 400 alloy method is the most favorable. Polarization tests with thin film electroformed nickel chloride showed that concentration polarization was only part of the problem. A major improvement was noted when the sintered nickel plaque was absent. Tests were conducted on pasted nickel chloride and nickel fluoride electrodes using graphite as a conductive diluent. Doping with sulphur on magnesium halide salts was tried. The use of PC-AlCl3 LiCl/Cl2 has not been satisfactory due to some reaction taking place with the lithium electrode. Two electrolytes using KPF6 were selected. Propylene carbonate is used for the nickel chloride system and dimethyl sulfoxide for the nickel fluoride system.
