Abstract
Provided are a separator for a secondary battery, a method for manufacturing the same, and a lithium secondary battery including the same, and particularly, a separator for a secondary battery which has sufficient thermal resistance and mechanical properties even without using a polymer-based organic binder lacking chemical stability, by adopting a metal alkanoate having a polar group as a binder for binding among particles forming a porous active layer and also between the porous active layer and a porous substrate. A method for manufacturing the same, and a lithium secondary battery including the same are also provided.
