description The present application provides a separator, which may include a substrate and a coating provided on at least one surface of the substrate, the coating including inorganic particles, first and second organic particles, organic-inorganic hybrid composite compound particles, and a first binder; where the first organic particles and the second organic particles may be embedded in the inorganic particles and the organic-inorganic hybrid composite compound particles and form bulges on a surface of the coating; the first organic particles and the second organic particles each may be independently one or more polymers containing one or more groups selected from: halogen, a phenyl group, an epoxy group, a cyano group, an ester group, an amide group, a hydroxyl group, a carboxyl group, a sulfonyl ester group, and a pyrrolidone group; and the first binder may include one or more linear copolymers containing a hydroxyl group and a carboxylate moiety.
