Abstract
Official abstract text for this publication.
An embodiment anode for an all-solid-state battery includes an anode current collector, and a coating layer disposed on the anode current collector, wherein the coating layer is a thin film including 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.
First claim
Opening claim text (preview).
What is claimed is: 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. 2. The anode of claim 1 , wherein the anode current collector comprises nickel, stainless steel, or combinations thereof. 3. The anode of claim 1 , wherein the coating layer comprises magnesium (Mg), aluminum (Al), silver (Ag), or combinations thereof. 4. The anode of claim 1 , wherein the coating layer is alloyed with lithium when the all-solid-state battery is in a charged state. 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. 6. The all-solid-state battery of claim 5 , wherein the anode current collector comprises nickel, stainless steel, or combinations thereof. 7. The all-solid-state battery of claim 5 , wherein the coating layer comprises magnesium (Mg), aluminum (Al), silver (Ag), or combinations thereof. 8. The all-solid-state battery of claim 5 , wherein the coating layer is alloyed with lithium when the battery is in a charged state. 9. The anode of claim 1 , wherein the anode does not include a separate anode active material layer.
