摘　　要：分析了钛酸锂(Li_4Ti_5O_(12))的晶体结构、嵌锂特性与电化学特性;介绍了目前制备Li_4Ti_5O_(12)的几种方法,主要是固相法和溶胶-凝胶法;其改性方面的研究不但包括掺杂、包覆,还包括结构的改变。Li_4Ti_5O_(12)作为零应变材料,具有优良的电化学性能,可用于提高其它电池材料的性能。最后提出了Li_4Ti_5O_(12)今后的研究方向。The crystal structure, lithium inserting performance and electrochemical property of lithium titanate（Li4Ti5O12） were analysed. The recent synthesizing methods were introduced and the main methods were solid-state method and sol-gel method. Modification of Li4Ti5O12 not only involved doping and coating, but also the changing of structure. Li4Ti5O12 could be used to improve the performances of other battery materials, because it is ＂zero strain＂ material and has excellent electrochemical properties . At last, the research directions were presented in this paper.
