摘要：

采用Ni(NO₃)₂·6H₂O和FeCl₃·6H₂O混合水热法合成纳米NiFe₂O₄粉体, 通过X射线衍射（XRD）和透射电子显微镜（TEM）对样品进行表征, 并对其进行充放电循环测试. 实验结果表明：生成的纳米NiFe₂O₄粉体为准晶型, 呈球状, 结晶度高, 晶型完好, 粒径分布均匀；第1,30,50,70次的充放电比容量分别为（997,1 019）,(726,750.2),(560.9,578.4),(514.8,528.2)(mA·h)/g, 表明NiFe₂O₄具有较好的电化学稳定性.

Abstract:

Using Ni(NO₃)₂·6H₂O and FeCl₃·6H₂O mixed hydrothermal method, we synthesized nanometer NiFe₂O₄powders, and characterized the samples by X-ray diffraction (XRD) and transmission electron microscopy (TEM). Meanwhile, in order to evaluate the stability of product, we tested the samples for charge and discharge cycle. The experimental results show that the nanometer NiFe₂O₄ power is spherical quasi\|crystal structure, high degree of crystallinity, crystalline intact and uniform particle size distribution; the 1st,30th,50th,70th specific capacity of the charge and discharge are （997,1 019）,(726,750.2),(560.9,578.4),(514.8,528.2)(mA·h)/g, which show that NiFe₂O₄ has good electrochemical stability.
