Claim 15:
16. An anode electrode structure, comprising:
a current collector comprising copper;
a lithium metal film formed on the current collector;
a copper film formed on the lithium metal film, in direct contact with the current collector, and having a thickness in a range from about 5 nanometers to about 40 nanometers; and
a protective film formed on the copper film;
wherein the protective film is a lithium-ion conducting film comprising lithium-ion conducting ceramic, lithium-ion conducting glass, lithium-ion conducting polymer, lithium- ion conducting liquid crystal, or combinations thereof; and
wherein the lithium-ion conducting film comprises one or more of aluminum oxide, LiPON, Li7La3Zr2O12 (LLZO), Li2S-P2S5, Li10GeP2S12, Li3PS4, (1-x)LiI-(x)Li4SnS4, (x)LiI- (1-x)Li4SnS4, (1-x)LiI-(x)Li4SnS4, (x)LiI-(1-x)Li4SnS4), wherein 0<x<1.
