    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.
