Anode material LiTiO-coke was prepared and tested for lithium-ion batteries. The as-prepared material exhibits excellent cycling stability and outstanding rate performance. Charge/discharge capacities of 266 mA h g at 0.100 A g and 200 mA h g at 1.000 A g are reached for LiTiO-coke. A cycling life-time test shows that LiTiO-coke gives a specific capacity of 264 mA h g at 0.300 A g and a capacity retention of 92% after 1000 cycles of charge/discharge.
