(FR) COMPOSITION POUR FILM POREUX DE BATTERIE SECONDAIRE NON AQUEUSE, FILM POREUX POUR BATTERIE SECONDAIRE NON AQUEUSE, ET BATTERIE SECONDAIRE NON AQUEUSE
Abstract
(EN) A composition for a non-aqueous secondary battery porous membrane including inorganic particles and a particulate polymer, wherein a volume-average particle diameter dof the inorganic particles is 0.1 µm or more and 1.0 µm or less, a weight ratio between the inorganic particles and the particulate polymer is within a range of 95:5 to 50:50, and a volume-average particle diameter dof the particulate polymer and the volume-average particle diameter dof the inorganic particles satisfy d/d> 1; and a non-aqueous secondary battery including the same.
(FR) L’invention concerne une composition pour film poreux de batterie secondaire non aqueuse qui contient des particules inorganiques et un polymère sous forme de particules. Le diamètre particulaire moyen en volume (d) desdites particules inorganiques est supérieur ou égal à 0,1μm et inférieur ou égal à 1,0μm. Le rapport massique dudit polymère sous forme de particules pour lesdites particules inorganiques se situe à l’intérieur d’une plage de 95:5 à 50:50. Le diamètre particulaire moyen en volume (d) dudit polymère sous forme de particules et le diamètre particulaire moyen en volume (d) desdites particules inorganiques, satisfont d/d>1. En outre, l’invention concerne une batterie secondaire non aqueuse équipée de cette composition.
