  "textContent": "Disclosed herein is a flame retardant separator for secondary batteries having an asymmetric structure, and more particularly, a flame retardant separator for secondary batteries having an asymmetric structure in which a hydroxide-based inorganic flame retardant is coated on only a surface facing a positive electrode.The present invention provides a separator, in which is capable of preventing the risk of lithium ions predominantly precipitated from a negative electrode in a lithium secondary battery, enhancing the flame retardant effect, and maintaining electrochemical properties in contrast with a conventional separator coated with inorganic matters, and a lithium secondary battery including the same.",
