Abstract
A negative electrode for a lithium metal battery includes a metal current collector substrate, a lithium metal layer formed on at least one surface of the metal current collector substrate, and a protective layer formed on the lithium metal layer. The protective layer includes a material capable of occluding and releasing lithium in an amount of 70% by weight or more based on a total weight of the protective layer.
