<P>PROBLEM TO BE SOLVED: To provide a sheath material for a power storage device which is easily manufactured and achieves high burst strength and seal strength of a heat seal part even when the heat seal part is swollen by an electrolytic solution, and to provide the power storage device using the sheath material for the power storage device. <P>SOLUTION: In a sheath material for a power storage device 1, an adhesive layer 12, a metal foil layer 13, a corrosion prevention treatment layer 14, an adhesive resin layer 15, and a sealant layer 16 are sequentially laminated on one surface of a base material layer 11, and olefinic system elastomer is dispersed on the adhesive resin layer 15. Further, contents for the power storage device, having a positive electrode, a separator, a negative electrode, an electrolytic solution, and a tab composed of a lead and a tab sealant, are sealed by the sheath material for the power storage device 1 so that a part of the tab is positioned at the exterior. <P>COPYRIGHT: (C)2013,JPO&INPIT |
