Abstract
The present disclosure relates to a separator for lithium secondary battery, a method for manufacturing 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 inhibits the metal column capable of growing on the surface of the negative electrode from moving toward the positive electrode, inhibits a micro-short circuit of the lithium secondary battery, and ultimately improves the lifetime of the lithium secondary battery. In addition, by controlling the type of filling the pores of the separator and the type of the polymer filling it, the output characteristics of the lithium secondary battery are secured and improved.
