Research Progress in Carbon Coating on Li4 Ti5 O12 Anode Materials

Keywords： Li4 Ti5 O12 , carbon coating , anode , lithium ion batteries , composite

尖晶石结构的Li4 Ti5 O12由于电压平台平稳、循环寿命长、“零应变”和安全性高等优点，成为锂离子电池的热门负极材料。然而纯Li4 Ti5 O12本身为绝缘体，导电性很差，倍率性能不佳，这限制了它的实际应用。研究表明，对Li4 Ti5 O12表面进行碳包覆可以有效改善其电化学性能。结合最近国内外研究情况，综述了表面碳包覆对Li4 Ti5 O12负极材料改性的研究进展，分析了不同的碳包覆方法、碳层厚度、碳结构和碳含量对Li4 Ti5 O12/C复合材料电化学性能的影响，希望促进Li4 Ti5 O12/C复合电极材料在锂离子电池领域的应用。

ABSTRACT:Spinel Li4 Ti5 O12 has become a promising anode material for lithium ion batteries because of its flat voltage, long cy-cle life,"zero starin" and high safety. However, the electronic conductivity of pure Li4 Ti5 O12 is very low, leading to bad rate per-formance, which limits its practical application. Studies have proven that carbon coating on Li4 Ti5 O12 can effectively enhance the electrochemical performance. In this review, we summarized the recent developments of modification of Li4 Ti5 O12 anode material by carbon coating based on the studies in China and foreign countries. Moreover, the effects of different coating methods, carbon coat-ing thickness, carbon structure and carbon content on the electrochemical properties of the Li4 Ti5 O12/C composite were analyzed, shedding light on the further application of the Li4 Ti5 O12/C composite as high-performance anode of lithium ion batteries.
