<P>PROBLEM TO BE SOLVED: To provide a laminate battery pack that is prevented from swelling or deforming owing to internal pressure without requiring any additional component, and has superior heat dissipation of heat in the battery to the outside. <P>SOLUTION: The laminate battery pack 1 includes a battery pack body portion 2, a first exterior material 10 including at least a thermoplastic resin film and a first soft aluminum foil of 15-120 μm in thickness as constituent layers, and a second exterior material 20 including at least a thermoplastic resin film and a second soft aluminum foil of 150-400 μm in thickness as constituent layers. The first exterior material 10 is molded in a solid shape having a housing case 17 capable of housing the battery pack body portion and a peripheral edge portion 18 for sealing extended outward from a peripheral edge of an upper-surface open hole of the housing case. The battery pack body portion 2 is housed in the housing case 17 of the first exterior material 10, the second exterior material 20 in a planar shape is arranged on the body portion 2, and a peripheral edge 28 of the second exterior material and the peripheral edge 18 of the first exterior material are joined together. <P>COPYRIGHT: (C)2012,JPO&INPIT |
