摘要： PURPOSE:To enhance the cycle life of a neg. electrode by making flat that side of a neg. electrode current collecting body which is in contact with a neg. electrode can, and by forming convex the side which is in contact with the separator side. CONSTITUTION:That side of a neg. electrode current collecting body 12 which is in contact with a neg. electrode can 9 is made flat, while the side in contact with the separator 3 side is made convex. Thus the neg. electrode current collecting body 12 of a flat type battery is accomplished, wherein the electrical treit of collecting electricity in the electrode active substance is made uniform by giving the bore 10 a greater thickness than the periphery 11 and by embodying the whole current collecting body 12 in convex form. Also the molding strength is enhanced. As a result, battery is concentrated locally in some electrode part to cause eduction of alkali metal, and frequency of occurrence of the dendritic short-circuiting reduced is, and further collapse due to expansion/ contraction associate with charging and discharging is inhibited. Thus the cycle life of the neg. electrode is enhanced.

摘要： PURPOSE:To increase mechanical strength with designed electrical performance retained by adding a specified amount of conductive powder to a negative electrode comprising a mixture of lithium alloy powder and an organic binder of a secondary battery. CONSTITUTION:Conductive powder containing at least one of carbon black and a conductive polymer is added to a negative electrode using lithium-lead- lanthanum(LiPbLa) powder as a negative active material and adding ethylene- propylene rubber(EPDM) thereto as an organic, binder so that the ratio of the total nitrogen absorbing area of the conductive powder to the weight of the organic binder is 3.5m /mg or more. The addition of the organic binder for increasing the mechanical strength of the negative electrode brings drop in its electrical performance, but the organic binder is selectively adsorbed by the carbon added. The mechanical strength of the negative electrode is increased with the electrical performance retained.

摘要： PURPOSE:To decrease the self discharge of a battery by increasing the viscosity of electrolyte through addition of such species of polymer as polyethylene glycol or the like in the electrolyte of a battery whose electrodes are made from high polymers having conjugate double bond. CONSTITUTION:As the examples of many high polymer compounds having conjugate double bond, polyacetylene, polyparaphenylene, polythienylene, polypyrrole etc., can be enumerated, but polyacetylene is a desirable one. As the material that increases the viscosity of electrolyte, the ones that perform only the said function and are not related to the reaction in the electrodes are preferable, e.g., polyethylene glycol, polyethylene oxide, polystyrene, polyvinyl acetate, polymethacrylic methyl, polyacrylonitrile and the like can be enumerated.

摘要： PURPOSE:To obtain a thin sheet-like, light weight power source system by combining together a solar cell with a sheet-like polymer secondary battery. CONSTITUTION:A power source system consists of a solar cell element 1, photoconductor 3, and polymer battery 4. The polymer battery 4 comprises positive current collector, positive electrode, separator containing electrolyte, negative electrode, negative current collector, and aluminium battery case. Positive and negative current collectors are constructed by spot-welding SUS304 expanded metal to SUS304 plate. Positive and negative electrodes are formed by pressing polyacetylene on the current collectors. Acetonitrile solution of (C2H5)4NBF4, for example, is used as electrolyte. The electrolyte is impregnated in the separator comprising polypropylene nonwoven fabric. The total thickness of the power source system including solar cell is about 10mm.. It is very thin.
