Abstract The present invention relates to a separator for a rechargeable lithium battery and a rechargeable lithium battery including same. Specifically, one embodiment provides a separator for a rechargeable lithium battery, the separator comprising: a substrate; and a heat-resistant layer positioned on at least one surface of the substrate, wherein the heat-resistant layer comprises heterogeneous particles having different shapes from each other, and the separator further comprises a shutdown filler positioned at the lower part, the inside part, the upper part, or two or more parts thereamong of the heat-resistant layer. La présente invention concerne un séparateur pour une batterie au lithium rechargeable et une batterie au lithium rechargeable le comprenant. Spécifiquement, un mode de réalisation concerne un séparateur pour une batterie au lithium rechargeable, le séparateur comprenant : un substrat ; et une couche résistante à la chaleur positionnée sur au moins une surface du substrat, la couche résistante à la chaleur comprenant des particules hétérogènes ayant des formes différentes les unes des autres, et le séparateur comprenant en outre une charge d'arrêt positionnée au niveau de la partie inférieure, de la partie intérieure, de la partie supérieure, ou de deux parties ou plus parmi celles-ci, de la couche résistante à la chaleur. 리튬 이차 전지용 분리막 및 이를 포함하는 리튬 이차 전지에 관한 것이다. 구체적으로, 일 구현예에서는 기재 및 상기 기재의 적어도 일면 상에 위치하는 내열층을 포함하고; 상기 내열층은 형태가 서로 다른 이종(異種) 입자들을 포함하고; 상기 내열층의 하부, 내부, 상부, 또는 이들 중 2 이상에 위치하는 셧다운 필러를 더 포함하는, 리튬 이차 전지용 분리막을 제공한다.
