Recently, as a promising anode material for lithium ion batteries the spinel lithium titanium (Li4Ti5O12)has attracted more and more attention due to its high reversible capacity(175mA·h/g) and its extremely small structural change during Li insertion / extraction [1-4].However, a main problem of Li4Ti5O12 is its poor rate performance attributed to its low electric conductivity (10-9S/cm) [5].Recently, H.E1-Shinawi [6] proposed a new anode material Li3Ti4NiCrO12 based on the structure of Li4TisO12.The crystal structure of Li3Ti4NiCrO12 can be viewed as a new substitution of Li4Ti5O12 in which Ti4+ and Li+ ions are replaced by Ni2+ and Cr3+ ions according to the following equation :Li4Ti5O12 + Ni2+ + Cr3+ =Li3Ti4NiCrO12 + Ti4+ + Li+However, the cyclic performance is not so satisfying.After 10 cycles, the specific capacity drops down to 80% of the initial value.
