Abstract
Lithium-containing anodes, high performance electrochemical devices, such as secondary batteries, including the aforementioned lithium-containing electrodes, and methods for fabricating the same are provided. In one implementation, an anode electrode is provided. The anode electrode comprises a first diffusion barrier layer formed on a copper foil. The first diffusion barrier layer comprises titanium (Ti), molybdenum (Mo), tungsten (W), zirconium (Zr), hafnium (H), niobium (Nb), tantalum (Ta), or combinations thereof. The anode electrode further comprises a wetting layer formed on the first diffusion barrier layer. The wetting layer is selected from silicon (Si), tin (Sn), aluminum (Al), germanium (Ge), antimony (Sb), lead (Pb), bismuth (Bi), gallium (Ga), indium (In), zinc (Zn), cadmium (Cd), magnesium (Mg), oxides thereof, nitrides thereof, or combinations thereof. The anode electrode further comprises a lithium metal layer formed on the wetting layer.
