Beschreibung
Zusammenfassung:	The present invention relates to a composite separator for a secondary battery, which can suppress a change in volume of a secondary battery due to volume expansion of a negative electrode material during charge/discharge, and a secondary battery including the same. The composite separator for a secondary battery comprises: a porous substrate; and a shear thickening fluid layer formed on one surface or both sides of the porous substrate. 본 발명은 다공성 기재 및 상기 다공성 기재 일면 또는 양면에 형성되는 전단 농화 유체층을 포함하는 이차전지용 복합분리막 및 이를 포함하는 이차전지에 관한 것이다.
