Zusammenfassung:A negative electrode for a rechargeable lithium battery that includes a negative active material layer including a carbon-based material having a peak of about 20 degrees to 30 degrees at a (002) plane in an X-ray diffraction pattern using a CuK± ray, and an SEI (solid electrolyte interface) passivation film including at least one material selected from an organic material and an inorganic material and having an average thickness of about 10 nm to about 50 nm on the surface of the active material layer of the electrode.
