Zusammenfassung:Disclosed is a separator for a lithium secondary battery, including: a porous polymer substrate; and a crosslinked porous coating layer formed on at least one surface of the porous polymer substrate, and including inorganic particles and a crosslinkable binder polymer crosslinked with each other through urethan crosslinking. It is possible to provide a separator having improved heat resistance as compared to the conventional separators and maintaining the adhesion to an electrode, and a lithium secondary battery including the same.
