Electrochemical behavior of MR-Te/C nanocomposite electrode.
(a) Voltage profiles of Te (current density: 10 mA g−1) and MR-Te/C nanocomposite electrodes (current density: 10 and 100 mA g−1). (b) Cycling performance of Te, Te/C nanocomposite and MR-Te/C nanocomposite electrodes at a cycling rate of 10 or 100 mA g−1. (c) Voltage profiles at various C rates for Li4Ti5O12 and MR-Te/C nanocomposite electrodes. (d) Plot of the discharge and charge capacity vs. cycle number for the Li4Ti5O12 and MR-Te/C nanocomposite electrodes at various C rates (Li4Ti5O12 - 1C: 190 mA h cm−3, MR-Te/C nanocomposite - 1C: 700 mA h cm−3).
