Spinel Li4Ti5O12 is an attractive anode material for lithium ion batteries due to its stable electrochemical characteristics. However, its low electrical conductivity is regarded as a critical disadvantage for commercialization. The addition of P123 with Cr3+ doping enhanced the surface area and the electrical conductivity, which improved the electrochemical properties of Li4Ti5O12. As-prepared samples were analyzed by X-ray diffraction, X-ray photoelectron spectroscopy, field-emission scanning electron microscopy, as well as BET and BJH analysis. Electrochemical properties were investigated by cyclic voltammetry, electrochemical impedance spectroscopy, powder conductivity measurement and cycle performance testing. P-Li4Ti4.95Cr0.05O12 showed excellent rate performance of 191, 189, 184, 175, 157, and 137 mAh/g at C-rates of 0.2, 0.5, 1, 2, 5, and 10 and high stable capacity retention of 147mAh/g at a C-rate of 10 after 300 cycles.
