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.
