Abstract
A separator includes a porous base, and a first coating layer on a surface of the porous base, the first coating layer including a (meth)acrylic acid ester-based polymer having a glass transition temperature of about 10° C. to about 60° C. The first coating layer may be positioned opposite to a cathode of the lithium secondary battery. The separator may further include a second coating layer on a surface of the porous base opposite to the first coating layer and comprising a (meth)acrylic acid ester-based polymer.
