1. A protected lithium metal electrode, comprising:
a lithium metal substrate; and
a protection layer, located on a surface of the lithium metal substrate, wherein the protection layer comprises:
a metal thin film, covering the surface of the lithium metal substrate, wherein the metal thin film consists of a metal selected from the group consisting of Ti, V, Cr, Zr, Nb, Mo, Hf, Ta, and W; and
an electrically-conductive thin film, covering a surface of the metal thin film, wherein a material of the electrically-conductive thin film is selected from one of nitride of a metal in the metal thin film, carbide of a metal in the metal thin film, a diamond-like carbon (DLC), and a combination thereof.
