Abstract
A method for preparing a separator, a separator prepared using the same, and an electrochemical device including the same. More specifically, stability of the separator may be reinforced by preparing the separator using a slurry prepared by pre-dispersing an inorganic material and a dispersion resin, and then mixing a binder thereto when preparing the separator.
Claims17
A method for preparing a separator, comprising:
- (S1) dispersing an inorganic material and a dispersion resin into a solvent to obtain a dispersion solution;
- (S2) mixing a binder with the dispersion solution to form a slurry;
- and
- (S3) coating the slurry on at least one surface of a substrate to form a coating layer.
