Title: LAMINATE FOR BATTERY
Abstract:
Provided is a laminate for a battery, which includes a metal base material layer and a polypropylene-based adhesive layer that satisfies at least the following conditions (1) to (4): (1) the adhesive contains 40-94 wt% of a propylene-based copolymer (A), 3-30 wt% of a butene-containing copolymer (B) and 3-30 wt% of an ethylene·α-olefin copolymer (C) (here, the total quantity of the copolymers (A), (B) and (C) is 100 wt%); (2) the copolymer (A) is a polymer having a melting point of 130ºC or higher, as measured by differential scanning calorimetry, and the overall proportion of structural units derived from ethylene is 4-25 mol% relative to a total of 100 mol% of all the structural units that constitute the copolymer (A) contained in the adhesive; (3) the copolymer (B) has a content of structural units derived from ethylene of less than 1 mol%, and has a melting point of 100ºC or lower, as measured by differential scanning calorimetry; and (4) the copolymer (C) has a content of structural units derived from ethylene of 50-99 mol%.
