A negative active material comprising lithium titanate oxide having an area ratio of a diffraction peak of a (111) plane that appears at 2&thetas;=18.3°±0.4 to a diffraction peak of a (311) plane that appears at 2&thetas;=35.5°±0.4, in an XRD spectrum, in the range of about 2.2:1 to about 5.5:1, a negative electrode comprising the negative active material, a lithium secondary battery comprising the negative electrode, and a method of preparing the negative active material. |
