摘要： 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.
