In this paper, Na2Li2Ti6O14 anode materials are synthesized by solid-state reaction and sol-gel method, respectively. Sol-gel formed Na2Li2Ti6O14 shows smaller particle size (0.05-0.1 mu m) than that (0.2-0.4 mu m) of samples prepared by solid-state reaction. Electrochemical results show that all the four samples have similar reduction peak at 1.20 V and oxidation peak at 1.35 V with average working potential of 1.28 V. Among all the as-obtained compounds, Na2Li2Ti6O14 synthesized by sol-gel method at 700 degrees C shows the highest initial charge specific capacity of 106.6 mA h g(-1). After 40 cycles, the reversible charge capacity can be maintained at 114.7 mA h g(-1). Moreover, this sample shows excellent rate properties with a high reversible charge capacity of 110 mA h g(-1) at 160 mA g(-1). The improved electrochemical performance is attributed to the proper particle size, high specific surface area and decreased electrochemical resistances. Therefore, Na2Li2Ti6O14 prepared from sal to gel technique will be a promising high-power anode material for rechargeable lithium-ion batteries. (c) 2014 Elsevier B.V. All rights reserved.
