Title:
A separator, its manufacturing method, and an electrochemistry element provided with it
Document Type and Number:
Japanese Patent JP5950914
Kind Code:
B2
Abstract:
Provided is a separator 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 formed by polymerization of a multifunctional phenol compound having at least two phenol groups with a multifunctional acyl halide compound of an aromatic compound having at least two acyl halide groups. The crosslinked polyamide coating layer hardly affects the air permeability of the separator. Also, the crosslinked polyamide coating layer has good hydrophilicity and wettability to an electrolyte, and thus may improve the performance of the battery. Also, the crosslinked polyamide coating layer has excellent resistance to heat and deformation, and thus may prevent the thermal shrinkage of the separator.
