Protected active metal electrode, a lithium metal electrode, and this electrode member having

A protected active metal electrode, a lithium metal electrode and having an electrode of this element. The protected active metal electrode comprises a protective layer located on the active metal substrate and the active metal substrate surface. This protective layer comprises at least a conductive thin film coated with a surfactant to the metal substrate and the metal thin film coated on the surface of the metal. Material of the metal film is a titanium, vanadium, chromium, zirconium, niobium, molybdenum, hafnium, tantalum or tungsten; material of the conductive film is a metal selected from the group comprising a metal nitride thin film, a metal thin film metal carbide diamond-like carbon film and a combination thereof.
