Abstract
(EN)
Provided is a battery comprising a separator containing inorganic particles for preventing a short circuit, wherein the inorganic particles are not removed readily from the separator. This battery is characterized by comprising a separator containing: a resin that is a base material and has holes; and inorganic particles each having a surface (A) facing each of the holes, and a surface (B) in contact with the resin, wherein the length of the surface (A) in the particle outer periphery is 50% or more than the length of the particle outer periphery in a cross-sectional SEM photograph of the separator.

La présente invention concerne une batterie comprenant un séparateur contenant des particules inorganiques pour empêcher un court-circuit, dans laquelle les particules inorganiques ne sont pas aisément retirées du séparateur. Cette batterie est caractérisée en ce qu'elle comprend un séparateur contenant : une résine qui est un matériau de base et comporte des trous; et des particules inorganiques ayant chacune une surface (A) faisant face à chacun des trous, et une surface (B) en contact avec la résine, la longueur de la surface (A) dans la périphérie externe des particules étant de 50 % ou plus de la longueur de la périphérie externe de particule dans une photographie MEB en coupe transversale du séparateur.
