| 摘 要： | 通过球磨CuF_2和MoO_3的混合物,制成CuF_2/MoO_3复合材料.通过X射线衍射(XRD)、扫描电镜(SEM)和电化学测试等研究CuF_2/MoO_3复合材料的结构和电化学性能.结果表明:MoO_3晶粒均匀地附着在CuF_2的表面,形成均匀的导电网,从而使制备的CuF_2/MoO_3复合材料具有高导电性,可作为锂一次电池正极活性材料.以0.1C倍率放电,截止电压为1.5 V,CuF_2/MoO_3复合材料放电比容量高达483mA·h/g,放电电位平台为2.5 V,明显高于CuF_2正极材料的278 mA·h/g,接近其理论容量528 mA·h/g.

| Abstract: | The CuF2/MoO3 composite was prepared by milling the mixture of CuF2 and MoO3. The structural and electrochemical properties of the CuF2/MoO3 composite were investigated by X-ray diffraction (XRD), scanning electron microscope (SEM) and electrochemical experiments. The results indicate that the MoO3 grains homogeneously coat on the surface of CuF2 and then form a high conductive matrix, which can be used for cathode material of lithium primary batteries. The specific discharge capacity of CuF2/MoO3 composite... |
