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.
