Negative electrode for lithium sulfur battery, method of preparing same and lithium sulfur battery comprising same

摘要

Disclosed is a negative electrode for a lithium sulfur battery. The negative electrode includes a lithium metal, a pre-treatment layer, and a protection layer for the lithium metal. The pre-treatment layer has a thickness of 50 to 5000 Å and includes a lithium ion conductive material with an ionic conductivity of at least 1x10<-10 >S/cm.
