PROBLEM TO BE SOLVED: To provide a battery-packaging material by which the break of seal of a battery can be suppressed effectively even if the battery is exposed to a high temperature.SOLUTION: A battery-packaging material comprises: a laminate having at least, a base material layer 1, a metal layer 3, a coat layer 4 and a sealant layer 5 in this order. The coat layer 4 is formed by a resin composition including an acid-modified polyolefin and a hardening agent. The sealant layer has a softening point of 100°C or higher, of which MFR at 230°C is 6 g/10 min.SELECTED DRAWING: Figure 1 |
