摘　　要：采用简单的静电纺丝方法制备了Ni/NiO/C负极材料。XRD证明该材料主要由NiO、Ni和无定形碳组成。SEM证明Ni/NiO/C的形貌呈纤维状,纤维的直径为400~500 nm。以Ni/NiO/C为锂电的负极材料,在100 mA g^(-1)的电流密度下,首次充电比容量可达到586.5 mAh g^(-1),循环50圈后的充电比容量仍可达到453.2 mAh g^(-1),容量保持率为77.27%。Ni/NiO/C anode materials were prepared by a simple electrospinning method.XRD results showed that the material was mainly composed of NiO,Ni and amorphous carbon.SEM results showed that the morphology of Ni/NiO/C was fibrous and the diameter of the fibers was about 400–500 nm.Under the current density of 100 mA g^(-1),the charge specific capacity of Ni/NiO/C anode can reach 586.5 mAh g^(-1) at first charge and 453.2 mAh g^(-1) after 50 cycles,the capacity retention rate was 77.27%.
