An investigation of Li₂TiO₃-coke composite anode material for Li-ion batteries

Anode material Li₂TiO₃-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^-1 at 0.100 A g^-1 and 200 mA h g^-1 at 1.000 A g^-1 are reached for Li₂TiO₃-coke. A cycling life-time test shows that Li₂TiO₃-coke gives a specific capacity of 264 mA h g^-1 at 0.300 A g^-1 and a capacity retention of 92% after 1000 cycles of charge/discharge.
