Abstract
A positive electrode material and a preparation method therefor, a positive electrode, a sodium battery, and an electric device are disclosed. The positive electrode material comprises a layered oxide represented by chemical formula Na<sub>a</sub>Ni<sub>b</sub>Fe<sub>c</sub>Mn<sub>d</sub>M<sub>e</sub>O<sub>f</sub>, wherein 0.8≤a≤1, 0≤b≤0.2, 0.25≤c≤0.5, 0.26≤d≤0.6, 0≤e≤0.1, 1.8≤f≤2, and M is a doped metal element. The preparation method for the positive electrode material comprises the step of sintering a Na<sub>a</sub>Ni<sub>b</sub>Fe<sub>c</sub>Mn<sub>d</sub>M<sub>e</sub>O<sub>f</sub> precursor. The positive electrode contains the layered oxide represented by the chemical formula, and the sodium battery contains the positive electrode. The electric device comprises the sodium battery. The layered oxide contained in the positive electrode material has high structural stability, gram capacity and energy density and good cycle performance. The sodium battery has high energy density and good cycle performance.
