A series of Li2BaTi6O14 samples are synthesized by a traditional solid-state method by calcining at different temperatures from 800 to 1000 degrees C. Structural analysis and electrochemical evaluation suggest that the optimum calcining temperature for Li2BaTi6O14 is 950 degrees C. The Li2BaTi6O14 calcined at 950 degrees C exhibits a high purity phase with an excellent reversible capacity of 145.7 mAh g(-1) for the first cycle at a current density of 50 mA g(-1) After 50 cycles, the reversible capacity can be maintained at 137.7 mAh with the capacity retention of 94.51%. Moreover, this sample also shows outstanding rate property with a high reversible capacity of 118 mAh g(-1) at 300 mA g(-1). The excellent electrochemical performance is attributed to the stable lithium storage host structure, decreased electrochemical resistance and improved lithium-ion diffusion coefficient. In-situ and ex-situ structure analysis shows that the electrochemical reaction of Li2BaTi6O14 with Li is a highly reversible lithiation delithiation process. Therefore, Li2BaTi6O14 may be a promising alternative anode material for lithium-ion batteries. (C) 2014 Elsevier B.V. All rights reserved.
