Li4Ti5O12作为锂离子电池负极材料电化学性能

Lithiated titanium complex oxide as negative electrode

    摘要
  • 摘要: 采用固相法合成了锂钛复合氧化物Li4Ti5O12研究了保温时间对其结构及电化学性能的影响.结果表明,保温时间为2,4h时样品的循环性能比较好,在80mA/g充放电下,30次循环后的比容量可高达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.
