Negative active material for rechargeable lithium battery and rechargeable lithium battery including same
Embodiments of the present invention are directed to negative active materials for lithium rechargeable batteries and to lithium rechargeable batteries including the negative active materials. The negative active material includes a crystalline carbon material having pores, and amorphous conductive nanoparticles in the pores, on the surface of the crystalline carbon, or both in the pores and on the surface of the crystalline carbon. The conductive nanoparticles have a FWHM of about 0.35 degrees (°) or greater at the crystal plane that produces the highest peak as measured by X-ray diffraction.
