Document Type and Number:
WIPO Patent Application WO/2022/164212
Kind Code:
A1
Abstract:
The present invention relates to a separator for a lithium secondary battery and a manufacturing method therefor. More specifically, the separator comprises an MOF layer formed by the Langmuir-Blodgett method and thus can prevent a shuttle phenomenon by a polysulfide released from a cathode containing a sulfur-containing material, thereby improving the cycle stability of the lithium secondary battery.
