Beschreibung
Zusammenfassung:	Provided is a separator for a lithium secondary battery, including: a porous polymer substrate; and a porous coating layer formed on at least one surface of the porous polymer substrate, wherein the porous coating layer includes flame-resistant particles, a highly heat resistant binder polymer and a fluorine-based binder polymer, and each of the flame-resistant particles, the highly heat resistant binder polymer and the fluorine-based binder polymer satisfies a predetermined content. In this manner, it is possible to provide a separator having improved heat resistance and mechanical properties despite its thin film structure.
