Adhesive Film For Metal Terminals And Method For Producing Same, Metal Terminal Provided With Adhesive Film For Metal Terminals, Outer Package Material For Power Storage Devices, Kit Comprising Outer Package Material For Power Storage Devices And Adhesive Film For Metal Terminals, And Power Storage Device And Method For Producing Same

Abstract: The present invention provides an adhesive film for metal terminals, the adhesive film being interposed between a metal terminal that is electrically connected to an electrode of a power storage device element and an outer package material for power storage devices, the outer package material sealing the power storage device element. With respect to this adhesive film for metal terminals, a resin layer A that forms at least one surface of this adhesive film for metal terminals contains an acid-modified polyolefin; and after heating this adhesive film for metal terminals at 200°C and 0.25 MPa for 16 seconds, the resin layer A has a crystallinity of 11 or more as determined with use of an X-ray diffractometer under the conditions described below. (Measurement conditions) · The angle of X-ray irradiation is 0.09° with respect to the surface (0°) of the resin layer A. · The measurement range is from the surface to the depth of 5 µm of the resin layer A. · The camera length of the X-ray detector is 500 mm; the X-ray wavelength is 0.92 Å; and the exposure time is 30 seconds.
