Title:
SEPARATOR FOR ELECTROCHEMICAL DEVICE, METHOD FOR MANUFACTURING SAME, AND ELECTROCHEMICAL DEVICE HAVING SAME
Document Type and Number:
WIPO Patent Application WO/2011/118984
Kind Code:
A2
Abstract:
The separator for an electrochemical device of the present invention comprises: a planar porous substrate; and a porous thin film coating layer, which is formed on at least one side of the planar porous substrate and includes a crosslinked polyester. The crosslinked polyester film does not influence the air permeability of the separator, enhances battery performance due to high affinity to an electrolyte and high wettability, and contributes to the prevention of heat-shrinkage of the separator due to superior resistance to heat and deformation.
