Abstract: A lithium metal negative electrode and a lithium metal battery including the lithium metal negative electrode. The lithium metal negative electrode includes a protective layer present on at least one surface of the negative electrode for stabilizing between the lithium metal and the electrolyte. The protective layer includes a polymer of alpha lipoic acid (ALA) and sulfur molecule (S8), a depolymerized product of the polymer, an inorganic sulfide-based compound, and at least one of an inorganic nitride-based compound, or an inorganic nitrate-based compound.
