Abstract
Provided are a separator coating composition, a method of manufacturing a separator using the same, and a separator and a lithium battery using the same. The separator coating composition includes a binder containing an aqueous crosslinking reactive poly(vinylamide)-based copolymer, a crosslinking agent having at least bifunctionality, 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 crosslinking reactive group-containing monomer. The separator coating composition may be used to prepare a separator capable of exhibiting high heat resistance even at a thinner coating thickness.
