摘要:
为改善氧化物负极材料的循环性能和充放电容量,采用沉淀法制备了作为锂离子电池负极材料的纳米CuO-Co3O4-NiO复合氧化物粉末。用X-射线衍射对其结构进行分析,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,采用沉淀法可以制备出粒径范围为10~30 nm的纳米CuO-Co3O4-NiO复合氧化物; 在40~50放电周期,放电容量保持率为94%。
Abstract:
To improve the cycle performance and charge/discharge capacity of oxide anode material,nano CuO-Co3O4-NiO composite oxide powder is synthesized by precipitation method as anode materials for lithium-ion batteries.Its crystalline structure is analyzed by X-ray diffraction,its morphology is characterized by transmission electron microscope,and its electrochemical performance is tested.The results show that nano CuO-Co3O4-NiO composite oxide can be obtained by precipitation method with the as-prepared particle size of 10-30 nm; the discharge capacity retention of nano CuO-Co3O4-NiO composite oxide is 94% from the 40th cycle to the 50th cycle.
