Low capacity is one of the most important factors limiting Li4Ti5O12 (LTO) development. Blending with superior theoretical capacities anode materials is the most effective way to increase its capacity. In this work, LTO/SiO blends with several ratios are prepared. Electrodes with moderate SiO contents (7LTO3SiO) can improve the stable capacity and rate performance of LIBs. 7LTO3SiO exhibits a discharging capacity of 191.0 mAh g(-1) at 2 A.g(-1), which is 81% higher than pure LTO. Moreover, 7LTO3SiO electrode retain 228.7 mAh.g(-1) after 100 cycles at 0.1 A.g(-1), which is only 188.1 mAh.g(-1) of pure LTO.
