Abstract: Nano-sized Li₄Ti₅O₁₂  was prepared at a low temperature with TiO₂ and lithium acetate as starting materials. Atom-sized blending was achieved by the liquid pre-dispersion and melting-soakage with ethyl alcohol as solvent. Calcination was carried out by different steps at relative low temperatures. The X-ray diffraction (XRD), scanning electron microscope (SEM) and size distribution tests showed that the  Li₄Ti₅O₁₂  was spinel structure with an average size of about 550 nm. The  Li₄Ti₅O₁₂  showed good electrochemical performance with the first charge-discharge capacity achieving 165 mA·h/g at 0.1 C and having a steady voltage and good cyclic performance. 
