Abstract:
(EN) The purpose of the present invention is to provide a non-aqueous secondary battery functional layer composition capable of forming a functional layer that has excellent heat shrinkage resistance, and that can cause non-aqueous secondary batteries to exhibit excellent cycle characteristics. This functional layer composition is a non-aqueous secondary battery functional layer composition including organic particles and a solvent, wherein the organic particles include a multifunctional ethylenically unsaturated monomeric unit at 55 to 90 mass%, and the volume average particle diameter of the organic particles is 50 to 370 nm.
(FR) L’objet de la présente invention est de réaliser une composition de couche fonctionnelle d’accumulateur non aqueux pouvant former une couche fonctionnelle dont la résistance à la thermorétraction est excellente, et qui peut faire en sorte que des accumulateurs non aqueux présentent d’excellentes caractéristiques de cycle. Cette composition de couche fonctionnelle est une composition de couche fonctionnelle d’accumulateur non aqueux incluant des particules organiques et un solvant, les particules organiques incluant entre 55 et 90 % en masse d’unités monomères éthyléniquement insaturées, et le diamètre moyen de particules en volume des particules organiques étant compris entre 50 et 370 nm.
