摘要: 采用固相法合成了鋰鈦復合氧化物Li4Ti5O12研究了保溫時間對其結構及電化學性能的影響.結果表明,保溫時間為2,4h時樣品的循環性能比較好,在80mA/g充放電下,30次循環后的比容量可高達159mAh/g.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 2 h and 4 h 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.
