Title (EN) POLYOLEFIN MICROPOROUS MEMBRANE
(FR) MEMBRANE MICROPOREUSE DE POLYOLÉFINE
(JA) ポリオレフィン微多孔膜
Abstract:
(EN) The purpose of the present invention is to provide a polyolefin microporous membrane with excellent self-discharge characteristics when built into a secondary battery as a separator. This polyolefin microporous membrane has a haze value of less than or equal to 90%, measured in accordance with JIS K 7136, and a piercing strength of greater than or equal to 1.96 N.
(FR) L’invention a pour objet de fournir une membrane microporeuse de polyoléfine excellente en termes de caractéristiques d’autodécharge, lorsqu’elle est intégrée à une batterie secondaire en tant que séparateur. Plus précisément, l’invention concerne une membrane microporeuse de polyoléfine qui présente une valeur de trouble mesurée conformément à JIS K 7136 inférieure ou égale à 90%, et une résistance au perçage supérieure ou égale à 1,96.
(JA) 本発明は、セパレータとして二次電池に組み入れた際の自己放電特性に優れたポリオレフィン微多孔膜を提供することを課題とする。 本発明は、JIS K 7136に準拠して測定されるヘーズ値が90%以下であり、突刺強度が1.96N以上であるポリオレフィン微多孔膜などによる。
