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.

Method for manufacturing separator, separator manufactured thereby, and electrochemical device comprising same

The present application relates to a separator and a battery comprising the same. A separator according to an exemplary embodiment of the present application includes: a porous substrate; and a first bonding layer pattern provided on at least one surface of the porous substrate, in which each pattern constituting the first bonding layer pattern is a pattern including a second bonding layer pattern having an aperture ratio of 5% or more and 40% or less.

Patterned separator and battery comprising same
