摘要
Li4Ti5O12作为锂离子电池的负极材料,在Li嵌入和脱出的过程中,其晶型不发生改变,被称之为“零应变材料”。因而具有优良的循环性能和平稳的放电电压,能够避免电解液分解现象或保护膜的生成,安全性和可靠性得以大大改善。详细描述了Li4Ti5O12的结构和电化学性能,介绍了Li4Ti5O12的两种合成方法以及掺杂改性研究的现状。
As an anode material for lithium ion battery, the crystal form of Li4Ti5O12 does not change. So it is regarded as a ＂zero strain＂ material. The lithium ion battery using Li4Ti5O12 as cathode material has excellent cycle performance and plateau voltage. Because Li4Ti5O12 can avoid electrolytes decomposition and solid-electrolyte interphase （SEI） creation, the safety and reliability of the material is improved as compared with carbon electrode. The preparation process, state-of-the-art doping modification and the effect of structure on electrochemical properties of Li4Ti5O12 are introduced.
