  "textContent": "The present invention relates to a separator for a lithium secondary battery and a lithium secondary battery comprising the same, more specifically, to a separator for a lithium secondary battery comprising a porous substrate and a coating layer formed on at least one surface of the porous substrate, wherein the coating layer comprises a defect-containing molybdenum disulfide. The separator for lithium secondary battery of the present invention adsorbs a lithium polysulfide through a coating layer comprising a defect-containing molybdenum disulfide and suppresses the growth of a lithium dendrite, thereby improving the capacity and lifetime characteristics of the lithium secondary battery.",
