Abstract
The present invention relates to negative electrode materials for rechargeable lithium batteries and to rechargeable lithium batteries including the same. The negative electrode materials improve the capacity characteristics and cycle-life characteristics of the rechargeable lithium batteries. The negative electrode material includes a negative active material capable of intercalating and deintercalating lithium ions, and the negative active material includes an oxide particle represented by LiMVOand having a full width at half maximum of a X-ray diffraction angle (2θ) at a (003) plane of 0.2 degrees or more as measured by X-ray diffraction analysis using a CuKαray.
