Abstract:
A separator for a secondary battery having a separator substrate and a coating layer formed on the separator substrate. The coating layer is on at least one surface of the separator substrate. The coating layer comprises an acrylate-based binder and an additive. The additive is a fluorine-based non-ionic surfactant, and provides a separator for a secondary battery with significantly improved electrolyte impregnation rate.
