Abstract

PROBLEM TO BE SOLVED: To provide an air secondary battery packaging material which excels in bondability between a package sheet and an oxygen permeable layer and also exhibits excellent oxygen permeability.SOLUTION: The air secondary battery packaging material comprises: a package sheet which consists of a laminate structure composed of an outer layer a metal foil layer and an inner layer including a thermoplastic rein film, and which has an oxygen intake opening provided therein, penetrating the outer layer, the metal foil layer and the inner layer; and an oxygen permeable film which is joined to the inner layer side on the periphery of the opening so as to cover the opening. On the bonded face of one of or both of the outer edge of the oxygen permeable layer and the periphery of the opening, a silane coupling agent containing a reactive functional group is applied.
【課題】外装シートと酸素透過膜との接合性に優れるとともに、酸素透過性の良好な空気二次電池用外装材を提供する。 【解決手段】外層と金属箔層と熱可塑性樹脂フィルムを含む内層とが積層されてなるとともに、外層と金属箔層と内層とを貫通する酸素取り込み用の開口部が設けられている外装シートと、開口部を覆うように開口部周辺部の前記内層側に接合される酸素透過膜と、を具備してなり、酸素透過膜の外縁部または開口部周辺部のいずれか一方または両方の接合面に、反応性官能基を有するシランカップリング剤が塗布されている空気二次電池用外装材を採用する。 【選択図】図2
