NOVELTY - Aqueous slurry comprises aqueous binder has polyvinyl alcohol-based polymer. USE - Aqueous slurry for coating hydrophobic separator. ADVANTAGE - The aqueous slurry capable of being uniformly coated on a hydrophobic separator, and also helps to convert the nature of the separator from hydrophobicity to hydrophilicity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a separator for a secondary battery coated with an aqueous slurry, which comprises aqueous binder, and comprises a polyvinyl alcohol-based polymer, such as polyvinyl alcohol, a polyvinyl alcohol derivative, and a copolymer comprises the polyvinyl alcohol.
