摘    要:以十六烷基三甲基溴化铵(CTAB)为模板,硝酸铁和硝酸铜为起始物,采用一步微波法,再经过简单的热处理制备了CuFe2O4负极材料,采用X射线粉末衍射(XRD)、扫描电子显微镜(SEM)、透射电子显微镜(TEM)、傅里叶红外光谱(FT-IR)等测试技术表征材料的结构和形貌。 电化学测试表明,在100 mA/g电流密度,0.01~3.0 V电压条件下,材料的首周嵌脱锂比容量分别为1202.2和873.2 mA·h/g,循环50周后,嵌锂比容量仍保持在近650 mA·h/g,显示出优异的电化学性能。

关 键 词:微波反应  电化学性能  铁酸铜  锂离子电池

Abstract:The copper ferrite was prepared by an one-pot microwave assisted sintering process with cetrimonium bromide(CTAB) as the template and copper and ionic nitrates as the reactants. The morphology and microstructure of the products were characterized by X-ray diffraction(XRD), scanning electron microscopy(SEM), transmission electron microscopy(TEM), and FT-IR spectroscopy. The as-prepared CuFe2O4 exhibits excellent electrochemical performance with the lithiation/delithiation capacity of 1202.2 mA·h/g and 873.2 mA·h/g(at the current 100 mA/g), respectively, and the capacities are maintained over 650 mA·h/g even after 50 charge/discharge cycles.
Keywords:microwave synthesis  electrochemical performance  ferrite  lithium ion battery
