The present disclosure relates to a separator for a lithium secondary battery, a method of manufacturing the same, and a lithium secondary battery including the same. Specifically, in one embodiment of the present disclosure, by filling the pores of the separator, the present invention physically suppresses the movement of metal pillars capable of growing on the surface of the negative electrode toward the positive electrode, suppressing the lithium secondary battery micro-short circuit, and ultimately improve the life of the lithium secondary battery. In addition, by controlling the type of pores filling the separator and the type of polymer filling the pores of the separator, the output characteristics of the lithium secondary battery are ensured and improved. |
