- - Separator of lithium-sulfur battery containing conductive polymer swollen by plasticizer lithium-sulfur battery comprising the same and manufacturing method for the same

摘要

The present invention provides a technique adjusting a polysulfide distribution and reducing a polysulfide ion elution and a shuttle phenomenon. A separation film of a lithium-sulfur battery comprises: a conductive polymer having an anion functional group; and a plasticizer impregnated in the conductive polymer. The conductive polymer is swollen by the plasticizer.
