Abstract

L'invention concerne une structure à fibres fines qui n'est pas affectée par des plissements ou des déformations de forme à cause d'une rupture ou d'une courbure même si elle est passée par un rouleau ou un guide de petit diamètre ou enroulée sur une bobine d'enroulement lors d'étapes de fabrication ou de traitement, et qui présente simultanément d'excellentes propriétés de perméabilité aux ions, de résistance aux courts-circuits et similaires, et qui est adaptée à être utilisée comme séparateur ou matériau isolant pour une batterie, un condensateur à double couche électrique, un condensateur électrique, ou un appareil similaire. L'invention concerne une structure à fibres fines comprenant une couche poreuse de fibres fines constituée de fibres fines polymériques avec un diamètre moyen entre 50 et 3000 nm, la structure à fibres fines étant caractérisée en ce que la résistance à la courbure de la structure à fibres fines selon une méthode en porte-à-faux à 45° est inférieure ou égale à 100 mm, et la taille moyenne des pores, l'épaisseur, la porosité, la masse surfacique, la perméabilité à l'air Frazier et le nombre de Macmillan dans la couche poreuse de fibres fines sont respectivement de 0,01 à 15 μm, 0,0025 à 0,3 mm, 20 à 90 %, 1 à 90 g/m2, moins de 46 m3/min/m2, et 2 à 15.
