Abstract
(EN) Disclosed is a separator for an electrochemical element, which is characterized by comprising a heat-resistant porous layer that is mainly composed of heat-resistant fine particles on at least one surface of a resin porous film that is mainly composed of a thermoplastic resin. The separator for an electrochemical element is also characterized in that: the resin porous film has a surface tension (wetting index) A of 35 mN/m or less; the heat-resistant porous layer is formed of a heat-resistant porous layer-forming composition that contains an aqueous medium and has a surface tension B of less than 29 mN/m; and the relation between the surface tension (wetting index) A and the surface tension B satisfies A > B.
(FR) L'invention concerne un séparateur pour élément électrochimique, caractérisé en ce qu'il comprend une couche poreuse résistant à la température, principalement composée de fines particules résistant à la température sur au moins une surface d'un film poreux de résine principalement constitué d'une résine thermoplastique. Le séparateur pour élément électrochimique est également caractérisé en ce que : le film poreux de résine présente une tension de surface (indice de mouillabilité) A égale ou inférieure à 35 mN/m ; la couche poreuse résistant à la température est formée d'une composition pour couche poreuse résistant à la température, contenant un milieu aqueux et présentant une tension de surface B inférieure à 29 mN/m ; et la relation entre la tension de surface (indice de mouillabilité) A et la tension de surface B satisfait à la relation A > B.
