Abstract
In order to solve the problem caused by leaching of lithium polysulfide, disclosed is a functional separator, a method of manufacturing the same, and a lithium secondary battery including the same, which can improve the capacity and life of the battery by coating a material capable of reducing lithium polysulfide on the separator surface. The functional separator includes a base separator; and a redox active polymer-conductive carbon composite layer on a surface of the base separator.
