A secondary battery porous membrane, manufactured by a slurry for secondary battery porous membrane, which is superior in coating priority and dispersibility of non-conductive organic particles, which improves cycle characteristic of the obtained secondary battery, which has high flexibility and can prevent powder falls, and which has less content of moisture amount; and non-conductive organic particles, which can be suitably used as a secondary battery porous membrane and has less content of metallic foreign particles. The slurry for secondary battery porous membrane comprises; a binder including a polymerized unit of vinyl monomer having a hydrophilic acid group, a non-conductive organic particle having a functional group, cross-linkable with the hydrophilic acid group and a solvent.
一种二次电池多孔膜,由一种二次电池多孔膜用浆料制造,该浆料在非导电有机颗粒的涂布优先性和分散性方面具有优势,可改善所得二次电池的循环特性,具有高柔韧性,可防止粉末掉落,且水分含量较少;以及非导电有机颗粒,可适当用作二次电池多孔膜,且金属异物颗粒含量较少。用于二次电池多孔膜的浆料包括:粘合剂(包括具有亲水性酸基的乙烯基单体聚合单元)、具有官能团的非导电有机颗粒(可与亲水性酸基交联)和溶剂。
