摘要： PURPOSE:To improve sealing property, in a sheet battery where a metal foil obtained by laminating polyethylene is used as the outer sheath, by arranging an insulator with softening point of 150 deg.C or higher between the polyethylenes and melting said polyethylenes. CONSTITUTION:The softening point of polyethylene 2 laminated to the external seath metal 1 is selected in the range from 100-150 deg.C. When the polyethylene is melted at this temperature for sealing, the metal 1 comes to contact with the lead 7, resulting in the defective insulation in the case of a battery. In view of preventing such phenomenon, an insulator 10 having the higher softening point than the polyethylene to be laminated, namely 150 deg.C or higher is inserted between such polyethylenes. As the insulator mentioned above, those obtained by lapping any of insulator such as fluorine resin sheet, glass, alumina or quartz fiber, etc. with the reformed polyethylene sheet and pressurizingly fusing it at the temperature near the softening point of reformed polyethylene can be listed. The unwoven fabric of polypropylene or reformed polypropylene sheet can be used directly.

Polypropylene nonwoven sheet is placed between both electrodes as a separator 3. Acetonitrile solution of (C2H5)4NBF4 which serves as electrolyte is filled in spaces of separator and a case 5. Silver-silver chloride covered with porous polymer is arranged as a reference electrode 1 within the battery. This polymer battery is charged with its negative electrode potential kept in potential at which hydrogen addition reaction does not occur.

摘要： PURPOSE:To retard the powdering and breaking of an electrode attendant on charge-discharge cycles and to lengthen the life of a negative electrode by using alpha-phase aluminium to which a third component which retards electrochemical reaction of aluminium with lihtium is added as a base material. CONSTITUTION:A base material is made of alpha-phase aluminium to which 0.1-20 wt% magnesium of alkali earth metal is added as a third component for retarding electrochemical reaction of aluminium with lithium. A degree that the third component retards the electrochemical reaction of aluminium is a level to lower the alloying start potential of alpha-phase aluminium with lithium by 0.05V or more than that of pure aluminium with lithium. As a result, a lithium-aluminium alloy layer is formed on the aluminium base material of a negative electrode 3, and the powdering and breaking of the electrode are retarded, and the life of the negative electrode is lengthened.
