Li4Ti5O12作为锂离子电池负极材料,在Li嵌入和脱出的过程中,其晶型不发生改变,被公认为“零应变”材料,具有优良的循环性能和使用寿命。详细地评述了蒸发溶剂法、Sol-gel法及水热法等软化学法合成UTi5O12的制备工艺及研究现状,并比较了它们的优缺点,探讨了Li4Ti5O12的未来发展方向。
As anode material for lithium ion battery,Li4Ti5O12 doesn't change its crystal structure during lithiation and de-lithiation, and therefore, it is regarded as a "zero strain" material. The lithium ion battery using Li4Ti5O12 as an anode material exhibits excellent cycle performance and service life. A review on the research progress in synthesis of Lh Li4Ti5O12 using soft chemical methods, such as solvent evaporation, sol-gel process and hydrothermal method, is reported in this paper. The advantages and disadvantages of different synthesis methods are compared and reviewed. At last, the development trend of Li4Ti5O12 are discussed.
