Abstract
Provided is a separator for an electrochemical device including a plate-like porous substrate, and a porous thin-film coating layer formed on at least one surface of the plate-like porous substrate and containing crosslinked polyester. The crosslinked polyester coating layer hardly affects the air permeability of the separator. Also, the crosslinked polyester coating layer has good hydrophilicity and wettability to an electrolyte, and thus improves the performance of the battery. Also, the crosslinked polyester coating layer has excellent resistance to heat and deformation, and thus prevents the thermal shrinkage of the separator.
