Abstract
A separator for a rechargeable battery includes a substrate and a coating layer on at least one surface of the substrate, wherein the coating layer includes a binder including an acrylic resin, the binder including the acrylic resin includes a carboxyl group-containing acrylic monomer and an acrylic acid derivative monomer, and the carboxyl group-containing acrylic monomer and the acrylic acid derivative monomer are present in a mole ratio of about 20:80 to about 80:20. The binder for a rechargeable battery has high heat resistance and strong adherence, and improves the cycling characteristics of the battery.
