Furthermore, elemental mapping confirmed the presence of all the elements in To confirm the formation of the NFM/C composite, the NFM/C-2 material was characterized by FE-TEM equipped with dual SDD-type EDS mapping. Figure 4 presents the FE-TEM image with the elemental distribution and EDS mapping spectra of the NFM/C- 2 material. Figure 4a shows the FE-TEM image of the NFM/C-2 material, while Figure 4b–f shows the elemental distributions of Na, Fe, Mn, O, and C elements, respectively. The elemental distributions indicate that all elements are evenly distributed in the NFM/C-2 7 of 12 the compound, as shown in Figure 4g. The chemical and valence states of 7alolf t1h2e elements in the as-synthesized NFM/C-2 material was investigated by XPS characterization, and the results are shown in Figure 5. As expected, the survey spectrum of the as-synthesized in the as-synthesized NFM/C-2 material was investigated by XPS characterization, and in the as-synthesized NFM/C-2 material was investigated by XPS characterization, and NFM/C-2 material indicates the presence of Na, Fe, Mn, O, and C, as shown in Figure 5a. the results are shown in Figure 5.

The peak at the binding energy of 284.00 eV confirms that the material possesses and 288.42 eV indicate that different chemical states of carbon are present in the as-syn- thesized material. The peak at the binding energy of 284.00 eV confirms that the material C–C bond and the peak at 288.42 eV indicates the O–C=O bond. These two types of carbon thesized material. The peak at the binding energy of 284.00 eV confirms that the material possesses C–C bond and the peak at 288.42 eV indicates the O–C=O bond. These two types bonding are beneficial for electrochemical reactions in batteries. The XPS results confirm possesses C–C bond and the peak at 288.42 eV indicates the O–C=O bond.
