    摘要： Disclosed are a negative active material for a rechargeable lithium battery that includes a core including silicon oxide represented by the following Chemical Formula 1; and a surface-treatment layer surrounding the core and including metal oxide represented by the following Chemical Formula 2; a method of preparing the negative active material; and a rechargeable lithium battery including the negative active material. The metal of the metal oxide is included in an amount of about 0.1 wt% to about 20 wt% based on the total weight of the negative active material for a rechargeable lithium battery.

    摘要： A negative electrode for a rechargeable lithium battery and a rechargeable lithium battery including the same, the negative electrode including a current collector; and an active material layer formed on the current collector. The active material layer includes a solid solution of a metallic component, and an active material that is capable of forming a lithium-included compound, the metallic component selected from Cu, Ti, a Cu-X alloy, a Ti-X alloy, and combinations thereof. In the alloys, X is selected from an alkaline metal, an alkaline-earth metal, a Group 13 element, a Group 14 element, a Group 15 element, a Group 16 element, a transition element excluding Cu, a rare earth element, and combinations thereof, and X is not Ti.
