Abstract

- Alithium ion storage battery, whereina container ofthe battery is a cylindric flexible external material whichis made of inaluminumplastic laminated film. A compound metallic oxide whichcanextrude / insert lithiumion and composition hereof are used as a positive electrode material, and the material which caninsert/ extrude lithiumion and composition hereof are used as anegative electrode material, a current collector of the positive electrode is made of an aluminum foil, a current collector of thenegative electrode is made ofa copperornickel foil. Amembrane, anegative electrode plate, a nembrane, a positive electrode plate are laminated and winded to a cylindric electrode core.The peripheral portion of the ;lectrode core is windedby a fixed adhesive tape.Apositive electrode tab and anegative electrode tab provided onthe wo end ofthe batteryrespectively are parallel to each otheroronthe same central line.Ahot melt adhesive film onthe tab s thermally sealed withthe aluminumplastic laminated firm. The battery canbe prevented from gas expansionor leak.
