Separator including laser-induced carbonized graphene layer and lithium-sulfur battery including the same

摘要

Disclosed is a separator for an electrochemical device. The separator includes a non-woven web substrate, wherein at least one surface of the non-woven web substrate includes an electrode reactive layer formed by carbonization of the non-woven web substrate from the surface of the non-woven web substrate to a predetermined depth, and the electrode reactive layer is disposed at the outermost side of at least one surface of both surfaces of the separator.
