Abstract
An anode, a lithium battery including the anode, and a method of preparing the anode. The anode includes a current collector; a first anode layer disposed on the current collector; a second anode layer disposed on the first anode layer; and an inorganic protection layer disposed on the second anode layer, wherein an oxidation/reduction potential of the first anode layer and an oxidation/reduction potential of the second anode layer are different from each other.
Claims20
An anode comprising:
- a current collector;
- a first anode layer disposed on the current collector;
- a second anode layer disposed on the first anode layer;
- and
- an inorganic protection layer disposed on the second anode layer,
- wherein an oxidation/reduction potential of the first anode layer and an oxidation/reduction potential of the second anode layer are different from each other.
A method of preparing an anode, the method comprising:
- disposing a first anode layer on a current collector;
- disposing, on the first anode layer, a second anode layer having an oxidation/reduction potential different from that of the first anode layer;
- and
- disposing an inorganic protection layer on the second anode layer,
- wherein the inorganic protection layer is disposed by atomic layer deposition to a thickness of about 100 nanometers or less.
