Separator for rechargeable lithium battery and rechargeable lithium battery including the same

Abstract

Example embodiments include a separator for a rechargeable lithium battery, and a rechargeable lithium battery including the separator. The separator includes a substrate, and a heat resistant adhesive layer on at least one surface of the substrate, wherein the heat resistant adhesive layer includes inorganic particles, a heat resistant binder, and a swellable adhesive binder. The swellable adhesive binder includes a first structural unit derived from a vinyl aromatic monomer, a second structural unit derived from alkyl acrylate, and a third structural unit derived from a phosphonate-based monomer.
