The negative active material for a rechargeable lithium battery includes lithium titanium oxide (Li4Ti5O12) having a tap density of about 1.2 g/cc to 2.2 g/cc. The lithium titanium oxide is prepared by a mechano-chemical treatment and a heat treatment at a low temperature of about 650° C. to 775° C. According to the present invention, lithium titanium oxide having high crystallinity and tap density can be prepared through a simple and low-cost solid-phase method, e.g., a mechano-chemical treatment, and thus an electrode with excellent electrochemical reactivity and high energy density per volume can be fabricated.
