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。

Abstract: 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 Li4Ti5Ol2 as cathode material has excellent cycle performance and plateau voltage. Because Li4Ti5Ol2 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 Li4Ti5Ol2 are introduced.
