    摘要:

    用共沉淀法制备FeNiHCF粉体,改变合成温度研究其对材料储钠性能的影响。使用X射线衍射(XRD)和场发射扫描电镜(SEM)表征了材料的微观结构和形貌。用FeNiHCF和Na分别作为正负极组装钠离子半电池。使用循环伏安(CV)和恒流充放电测试手段表征样品的储钠性能,结果表明,合成温度的改变会影响材料的微观形貌和储钠性能,60℃合成的FeNiHCF初始钠含量、比容量、循环稳定性均为最佳。

    Abstract:

    FeNiHCF was prepared by co-precipitation method, and the influence of synthetic temperature on the sodium storage performance was studied. The microstructure and micromorphology of the as-prepared FeNiHCF were characterized by XRD and SEM. An sodium ion half cell was constructed with FeNiHCF as cathode and sodium as anode, respectively. The sodium storage performance of the prepared FeNiHCF was characterized by cyclic voltammetry and galvanostatic charge/discharge test. The change of synthetic temperature affects the micromorphology and sodium storage performance of the material. The initial sodium content, specific capacity and cycle stability of FeNiHCF prepared at 60℃ are the best. The FeNiHCF prepared at 60℃ is a very promising cathode material for sodium ion batteries.
