采用低温水热法制备了纳米镍铁氧体(NiFe2O4)。用X射线衍射仪、透射电子显微镜、高分辨电子显微镜和氮气物理吸附等手段对样品的晶相、形貌和比表面积进行了表征。得到的NiFe2O4样品的颗粒尺寸在5-15 nm之间。测试了纳米NiFe2O4作为锂离子电池负极材料的电化学性能。结果表明，由纳米NiFe2O4制备的负极首次放电容量可达1314mAhg−1，当电流密度为0.2mAcm−2时，循环2次和3次后的放电容量分别降至790.8mAhg−1和709.0mAhg−1。比表面积达111.4m2g−1。根据循环伏安(CV)实验结果，对锂与镍铁氧体的反应机理进行了讨论。
Nano-sized nickel ferrite (NiFe2O4) was prepared by hydrothermal method at low temperature. The crystalline phase, morphology and specific surface area (BET) of the resultant samples were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), high-resolution transmission electron microscopy (HRTEM) and nitrogen physical adsorption, respectively. The particle sizes of the resulting NiFe2O4samples were in the range of 5–15nm. The electrochemical performance of NiFe2O4nanoparticles as the anodic material in lithium ion batteries was tested. It was found that the first discharge capacity of the anode made from NiFe2O4nanoparticles could reach a very high value of 1314mAhg−1, while the discharge capacity decreased to 790.8mAhg−1and 709.0mAhg−1at a current density of 0.2mAcm−2after 2 and 3 cycles, respectively. The BET surface area is up to 111.4m2g−1. The reaction mechanism between lithium and nickel ferrite was also discussed based on the results of cycle voltammetry (CV) experiments.
