Abstract
In order to solve the problems caused by lithium polysulfide leaching from the positive electrode, disclosed is a catalytic site-introduced functional separator, a method of manufacturing the same, and a lithium secondary battery including the same, which can improve the capacity and lifetime of the battery by coating a material, which can act as a reduction catalyst for lithium polysulfide, on the surface of the separator. The catalytic site-introduced functional separator includes a base separator and a catalytic site-containing coating layer located on the surface of the base separator.
