摘要/Abstract

摘要： 以水滑石为前驱体合成微米花/纳米片多级结构过渡金属复合氧化物CoFe2O4，一种高性能锂离子电池负极材料。通过X射线衍射仪(XRD)、扫描电子显微镜(SEM)和透射电子显微镜(TEM)等技术手段对其进行结构表征，发现得到的复合氧化物为单一晶相，且具有多级结构。电化学性能测试表明，得到的负极材料具有高比容量和倍率性能。通过还原氧化石墨烯(rGO)对CoFe2O4进行表面包覆制备CoFe2O4/rGO，其循环稳定性得到大幅度提高。

Abstract: Binary transition metal oxide CoFe2O4 as a high capacity anode material for lithium-ion batteries with the microflower/nanosheet hierarchical structure was synthesized by layered double hydrotalcite-like precursors. The CoFe2O4 and reduced graphene oxide（rGO）coated CoFe2O4(CoFe2O4/rGO) materials were characterized by powder X-ray diffraction(XRD), scanning electron microscope(SEM), transmission electron microscope(TEM) techniques. The electrochemical performances of the CoFe2O4 and CoFe2O4/rGO electrodes were examined in terms of cyclic voltammetry and discharge/charge profiles. The electrodes exhibit high capacity and rate capacity. Furthermore, the cyclic performance of CoFe2O4/rGO electrode is better than that of the CoFe2O4 electrode.

Key words: lithium-ion batteries, anode materials, binary metal oxides, hierarchicalstructure, electrochemical performance
