| Abstract: | Lithiated titanium complex oxide Li4Ti5O12 was prepared by solid-state method. The influence of reaction time on the structure and electrochemical performance of Li4Ti5O12 was investigated. The samples with the reaction time of 2h and 4h show a good reversibility, and their specific capacity after 30 cycles is as high as 159 mAh/g when charged and discharged at 80 mA/g. |
