摘要： Provided is a separator including a plate-like porous substrate, and a porous thin-film coating layer formed on at least one surface of the plate-like porous substrate, and containing crosslinked polyester formed by polymerization of a multifunctional phenol compound having at least two phenol groups with a multifunctional acyl halide compound of an aromatic compound having at least two acyl halide groups. The crosslinked polyamide coating layer hardly affects the air permeability of the separator. Also, the crosslinked polyamide coating layer has good hydrophilicity and wettability to an electrolyte, and thus may improve the performance of the battery. Also, the crosslinked polyamide coating layer has excellent resistance to heat and deformation, and thus may prevent the thermal shrinkage of the separator.
摘要翻译：提供一种隔板，其包括板状多孔基材和形成在板状多孔基材的至少一个表面上的多孔薄膜涂层，并且含有通过聚合具有至少两个苯酚基团与具有至少两个酰卤基团的芳族化合物的多官能酰卤化合物。交联的聚酰胺涂层几乎不影响隔膜的透气性。此外，交联的聚酰胺涂层对电解质具有良好的亲水性和润湿性，因此可以提高电池的性能。此外，交联的聚酰胺涂层具有优异的耐热变形性，因此可以防止隔膜的热收缩。

摘要： A separator includes a monolayer-type polyolefin-based micro-porous film having a porosity of 40 to 60%, an average pore diameter of 60 nm or less, and an air permeability of 350 s/100mL or less; and a porous coating layer formed on at least one surface of the micro-porous film and made of a mixture of a plurality of inorganic particles and a binder polymer. An electrochemical device having the above separator has excellent thermal stability and allows a high power while minimizing the occurrence of leak current.

摘要： A separator includes a porous substrate having a plurality of pores; and a porous coating layer formed on at least one surface of the porous substrate and made of a mixture of a plurality of inorganic particles and a binder polymer, wherein the binder polymer includes a first polyvinylidene fluoride based copolymer having solubility of 25 weight % or more with respect to acetone at 35° C.; a second polyvinylidene fluoride-based copolymer having solubility of 10 weight % or less with respect to acetone at 35° C.; and a polymer having a cyano group. This separator decelerates deterioration of life span of an electrochemical device, and prevents disintercalation of inorganic particles in the porous coating layer, thereby improving safety of the electrochemical device.
