More Information
Summary:Disclosed are a functional separator capable of improving capacity and life of a battery by coating a material capable of reducing lithium polysulfide on a surface of the separator, a manufacturing method thereof, and a lithium secondary battery including the same. The functional separator comprises: a base separator; and a polyethylene oxide (PEO)-conductive carbon composite layer positioned on the surface of the base separator. 분리막 표면에 리튬 폴리설파이드의 환원이 가능한 물질을 코팅시킴으로써 전지의 용량과 수명을 향상시킬 수 있는, 기능성 분리막, 그 제조 방법 및 이를 포함하는 리튬 이차전지가 개시된다. 상기 기능성 분리막은, 베이스 분리막; 및 상기 베이스 분리막의 표면에 위치하는 폴리에틸렌옥사이드(PEO)-전도성 탄소 복합층;을 포함한다.
