摘要： Disclosed is a nonaqueous electrolyte battery including a battery element contained in an outer covering member composed of a laminated film and sealed therein by heat seal, and a gas absorbable material interposed between the outermost layer of the outer covering member and the battery element. Such a battery is advantageous in that even if gas occurs in the battery element, the laminated film as the outer covering member is prevented from being swelled.

摘要： A nonaqueous electrolyte battery is disclosed which has an improved volume energy density and satisfactory impact resistance, a heat radiating characteristic and producibility. The battery element is accommodated in a casing constituted by a laminate film so as to be sealed by welding. Electrode-terminal leads electrically conducted to electrodes which constitute the battery element are sandwiched by welded portions so as to be exposed to the outside portion of the casing. A control circuit of the battery is mounted on a welded portion of the casing. Since the control circuit of the battery is mounted on the welded portion of the casing, the space in the battery in which the battery element is not present can effectively be used. Therefore, the volume efficiency can considerably be improved.
