Title: SEPARATOR AND LITHIUM-SULFUR BATTERY COMPRISING SAME
Abstract:
The present invention relates to a separator and a lithium-sulfur battery comprising same, the separator having a coating layer, in which graphene oxide and boron nitride are alternately stacked, on at least one side of a porous substrate and thereby being capable of simultaneously solving problems caused by lithium polysulfides and lithium dendrites occurring in conventional lithium-sulfur batteries.
