The heat-treatment changed its morphological, structural and charging/discharging performance. The product obtained upon the treatment at 300 °C, consisting of uniform, rod-shaped particles, 100-150 nm in diameter and 300-800 nm in length, displayed the best electrochemical performance in aqueous LiNO3 solution. Its initial discharge capacity amounted to 136.8 mAh g-1 at a rate of C/5, which upon 50 charging/discharging cycles decreased for only 12%. © 2011 Elsevier Ltd. All rights reserved. |
