  "textContent": "A separator for a secondary battery includes a porous polymer substrate and a porous coating layer disposed on at least one surface of the porous polymer substrate. The porous coating layer includes inorganic particles, a binder polymer, and a dispersant. The binder polymer includes at least three types of fluorine-based polymers. The dispersant includes a first dispersant and a second dispersant, the second dispersant having a lower weight average molecular weight than the first dispersant. Also provided is a method of manufacturing a separator for a secondary battery.",
