摘　　要：为改善氧化物负极材料的循环性能和充放电容量，采用熔融盐法制备了作为锂离子电池负极材料的纳米NiO／C复合物粉末。用X射线衍射光谱法对其结构进行分析。透射电镜对其形貌进行表征，并对其电化学性能进行测试。结果表明。采用熔融盐法可以制备出粒径为50～70nm的纳米NiO／C复合物；在40-50个放电周期，放电容量保持率为95％。To improve the cycle performance and charge/discharge capacity of oxide material, nano NiO/C composites were synthesized by molten salt method as anode materials for lithium-ion batteries. Its crystalline structure was analyzed by X-ray diffraction, its morphology was characterized by transmission electron microscope, and its electrochemical performance was tested. The results show that nano NiO/C composites can be obtained by molten salt method with the as-prepared particle size of 50-70 nm; the discharge capacity retention of nano NiO/C composites is 95% from the 40th cycle to the 50th cycle.
