1. An anode for an all-solid-state battery, the anode comprising:
an anode current collector; and
a coating layer disposed on the anode current collector,
wherein the coating layer is a thin film consisting of at least one metal selected from the group consisting of alkaline earth metals, Group 4 to 9 transition metals, Group 13 metals, and combinations thereof, and
wherein the anode excluding the anode current collector has a thickness of 300 nm to 500 nm.
 
5. An all-solid-state battery, comprising:
a cathode;
an anode comprising:
an anode current collector; and
a coating layer disposed on the anode current collector,
wherein the coating layer is a thin film consisting of at least one metal selected from the group consisting of alkaline earth metals, Group 4 to 9 transition metals, Group 13 metals, or combinations thereof, and
wherein the anode excluding the anode current collector has a thickness of 300 nm to 500 nm; and
a solid electrolyte layer disposed between the cathode and the anode, wherein the solid electrolyte layer is laminated to contact the coating layer of the anode.
