Abstract
In embodiments of the present invention, a coating layer including a fluorinated graphene oxide (FGO) material is coated on a separator and the separator is used for a lithium metal battery. Accordingly, it is possible to prevent growth of dendrites of a lithium metal negative electrode by forming lithium fluoride with good ion conductivity during use of the lithium metal battery, and to improve energy density and stability of the lithium metal battery compared to using a conventional ceramic material as a coating layer and thus greatly contribute to commercialization of the lithium metal battery.
