Abstract
Provided are a composition for coating a separator, a method of preparing a separator using the same, a separator, and a lithium battery employing the separator. The composition for coating a separator includes a binder including an aqueous cross-linking reactive poly(vinylamide)-based copolymer, a cross-linker, inorganic particles, and water, wherein the poly(vinylamide)-based copolymer includes a repeating unit derived from a vinylamide monomer, and a repeating unit derived from a cross-linking reactive group-containing monomer. The composition for coating a separator may provide a separator having high thermal resistance characteristics.
