XRD results show that the co-doping of Mg2+ and F− reduces the mixing degree of cations and increases the lattice parameters. A small amount of Mg2+ and F− co-doping does not affect the layered structure of NFA materials. The results of SEM, EDS, and elemental spectrum showed that Mg and F elements were evenly dispersed on the surface of the material and successfully doped into the crystal structure of the material. The co-doping of Mg2+ and F− did not damage the surface of NFA primary particles. XPS results further confirmed that Mg2+ and F− were introduced successfully into NFA materials. Compared with the original NFA material, the co-doping of Mg2+ and F− significantly improved the electrochemical performance of the pristine material. Electrochemical results show that co-doping has the best first discharge-specific capacity, first-coulomb efficiency, and cycle life. The first discharge-specific capacity and coulomb efficiency at 0.1 C and 10 C were 171.8 mAh g−1, 88.1%, and 143.4 mAh g−1, 71.72%, respectively.
