英文摘要	以无定形的水合二氧化钛为前驱物,水热法合成了200～400nm大小的Li4Ti5O12纳米片作为锂离子电池负极材料.XRD(X射线衍射)、SEM(扫描电子显微镜)和TEM(透射电镜)分析表征样品的物相结构、表观形貌;循环伏安、充放电循环和电化学交流阻抗技术分别测定该纳米Li4Ti5O12在有机电解液和室温离子液体S114TFSI电解液中的电化学性能.结果表明,该材料具有较高的放电容量和良好的循环性能,有望成为锂二次电池新型负极材料.; Spinel lithium titanate(Li4Ti5O12) nanosheets with a size range of 200 ～400 nm were synthesized by hydrothermal process from the amorphous hydrous titanium oxide precursors.The as-prepared products were characterized by X-ray powder diffraction(XRD),scanning electron microscopy(SEM) and transmission electron microscopy(TEM).The electrochemical behaviors of Li4Ti5O12 electrode in conventional organic electrolyte and ionic liquid electrolyte were investigated by using cyclic voltammetry,galvanostatic charge-discharge and AC impedance techniques.The experimental results indicate that the as-prepared nanostructured Li4Ti5O12,evaluated as anode material,exhibited good reversibility and cycle performance.It is expected to be a potential anode material for commerical battery applications.; 作者联系地址：上海交通大学化学化工学院;; Author's Address: School of Chemistry and Chemical Technology,Shanghai Jiao Tong University,Shanghai 200240,China
