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

Abstract

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.
