    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.

    摘要： Provided is a battery capable of preventing the entry of water even if a sealing width is reduced. A battery element comprising a cathode and an anode is accommodated in a film-shaped casing. The casing includes a metal layer, a resin layer disposed on a side of the metal layer closer to the battery element with an adhesive layer in between, and a resin layer disposed on a side of the metal layer opposite to the side where the resin layer is formed with an adhesive layer in between. The adhesive layer has a water vapor transmission rate of 800 g/m2·day or less for a thickness of 25 μm at 40° C. and 90% RH and a thickness of 10 μm or less. Thereby, even if the sealing width is reduced, the entry of water into the battery can be prevented.

    摘要： A battery pack includes a non-aqueous electrolyte secondary battery, a rigid covering member, and a protection circuit board. The secondary battery includes a battery element and a flexible covering member formed of a first laminated film composed of a first heat-bonding layer, a first metal layer, and a first outer covering layer laminated successively. The flexible covering member is sealed along around the battery element while leaving electrode terminals of the positive and negative electrodes extended outside the battery element. The rigid covering member is formed of a second laminated film composed of a second heat-bonding layer, a second metal layer, and a second outer covering layer laminated successively. The flexible covering member and the rigid covering member are bonded with an adhesive strength equal to or higher than atmospheric pressure and with a peel strength equal to or lower than a breaking strength of the flexible covering member.
