Abstract: A battery packaging material includes a laminate that includes at least a base material layer, a metal layer, an insulating layer, and a sealant layer laminated in this order. The insulating layer is formed of a resin composition containing a modified polyolefin resin modified with an unsaturated carboxylic acid or acid anhydride thereof and has a hardness, when measured by using a nanoindenter and pressing an indenter 5 μm into the insulating layer from a cross-section of the laminate in the laminating direction thereof, that ranges from 10 MPa to 300 MPa. In the sealant layer, an elastic modulus, when measured by using a nanoindenter and pressing an indenter 5 μm into the sealant layer from a cross-section of the laminate in the laminating direction thereof, ranges from 100 MPa to 1000 MPa.

Abstract: Provided is a cell packaging material having a high insulating performance and durability. A cell packaging material comprising a layered body provided with at least a substrate layer, a metal layer, an adhesive layer, and a heat-fusible resin layer in the stated order. The adhesive layer has a resin composition that contains an acid-modified polyolefin and an epoxy resin. In probe displacement amount measurements involving the use of a thermal mechanical analyzer, when a probe is placed on the surface of the adhesive layer at an end part of the cell packaging material and the probe is heated from 40° C. to 220° C., the position of the probe does not drop in relation to the initial value.
