Abstract
(EN)
[Problem] To provide a secondary battery porous membrane that has superior heat resistance and flexibility and contributes to improvements in battery cycle characteristics. Also provided is a secondary battery having high cycle characteristics that uses this porous membrane. [Solution] This secondary battery porous membrane contains nonconductive particles and a binder. The binder is characterized by being formed from a polymer containing a nitrile group, a novel group, and a C4+ straight-chain alkylene structural unit in the same molecule and the nitrile group content in the polymer constituting the binder being 1 - 25% by mass, with the iodine value of the polymer being 0 mg/100 mg - 30 mg/100 mg.

L'invention a pour but de fournir une membrane poreuse de batterie secondaire présentant une résistance à la chaleur et une souplesse supérieures et contribuant à améliorer les caractéristiques de cycle de charge de la batterie. L'invention concerne également une batterie secondaire ayant de bonnes caractéristiques de cycle de charge utilisant cette membrane poreuse. Ce but est atteint par le fait que cette membrane poreuse de batterie secondaire contient des particules non conductrices et un liant. Le liant est caractérisé en ce qu'il est formé d'un polymère contenant un groupe nitrile, un nouveau groupe, et un maillon structurel d'alkylène à chaîne droite en C4+ dans la même molécule, la teneur en groupes nitriles du polymère constituant le liant étant de 1 à 25 % en masse, l'indice d'iode du polymère étant de 0 mg/100 mg à 30 mg/100 mg.
