EXAMPLE - A slurry was produced using cadmium powder, sodium phosphate powder, nylon short fiber and polyvinyl alcohol with 10C olefin side chain and degree of saponification of 88 mol%. The slurry was allowed to stand after production, and time required for sedimentation was measured. The slurry was applied on a punching metal, and an electrode was produced. The battery comprising the electrode was charged at 1 CmA, and battery internal pressure at the time of charging was measured. Time for sedimentation was 1015 min. The battery using the electrode had internal pressure of 0.28 MPa.
EXAMPLE - Lithium carbonate and cobalt carbonate were mixed at lithium to cobalt molar ratio of 1.1. The resulting blend was heated at 800degreesC for 6 hours. The baked product obtained was cooled, pulverized and heated at 800degreesC for 6 hours, and lithium cobalt oxide (LiCoO2) was obtained. Lithium cobalt oxide, and 3 weight% (wt.%) of ethylene-propylene-cyclic diene ternary polymer in hexane was mixed with 7 wt.% of acetylene black and 90 wt.% of electroconductive agent, and an anode mixture was prepared. The anode mixture was applied on a stainless steel substrate to a thickness of 100 mum, and dried, and a positive electrode plate which has 0.26 mm thick anode layer was obtained. A novolac resin was baked at 950degreesC in nitrogen atmosphere, carbonized and pulverized at 2000degreesC, and powder with mean diameter of 10 mum as carbonaceous material was obtained. Carbonaceous material and binder containing carboxymethyl cellulose with average polymerization degree of 1000, mean molecular weight of 50000 and etherification degree of 1, and tetrafluoroethylene-diethylene fluoride in a weight ratio of 1:2, were dispersed in a ester type solvent, in a weight ratio of 96:4, and a negative electrode slurry was obtained. The slurry was applied on a stainless steel plate and dried. The negative electrode which has a negative electrode layer with a thickness of 0.2 mm, was manufactured. An insulator was arranged on the bottom part of a stainless steel container. Negative electrode, separator and positive electrode were laminated in order to obtain an electrode group. The electrode group was accommodated in the container, and a non-aqueous solvent secondary battery with excellent charging and discharging cycle life, capacity and stable battery performance, was obtained.
TECHNOLOGY FOCUS - POLYMERS - Preferred Film: The reinforcement film consists of a fluororesin or a polypropylene, and has thickness of 5-50 mum.
