摘　　要：Li4Ti5O12由于其长的循环寿命及高的安全性能,成为二次锂离子电池,特别是动力电池的优秀候选材料。本文综述了负极材料Li4Ti5O12的结构、合成方法、物理特性和电化学性能,着重介绍了各种元素的掺杂对Li4Ti5O12循环容量、充放电电压平台及高倍率性能的影响。Due to its long cycling life and high safety properties, Li4Ti5O12 has become an exceitent candidate for anode materials used in secondary lithium ion batteries, especially in vehicle batteries. The structure characteristics, synthesis, physical properties and electrochemical performance of Li4Ti5O12 anode materials were reviewed in this paper. The emphasis is mainly focused on the doping effects on the reversible capacity, the potential plateau and the rate-capability of Li4Ti5O12.
