Abstract
Provided are a composition for coating a separator, a method of preparing a separator by using the same, a separator, and a lithium battery employing the separator. The composition for coating a separator includes: a polyacrylamide-based copolymer including a cross-linking reactive group; inorganic particles; and water, and the cross-linking reactive group includes at least two functional groups cross-linkable with each other. The composition for coating a separator may be used as a one-component type without a crosslinker, and a separator having high thermal resistance characteristics may be prepared by using the composition.
