The cathode active material has a chemical formula of NaNiFeMnMAO, where M is selected from the group consisting of Ti, Al, Mg, Ca, Zr, Y, Zn, Nb, W and combinations thereof, A is selected from the group consisting of B, P, C and combinations thereof, 0.80≤x≤1.40, 0.05≤y≤0.95, 0.05≤z≤0.95, 0.05≤g≤0.95, 0.01≤h≤0.50, and 0.01≤m≤0.30. By adding M and A elements to the ternary iron-manganese-nickel cathode active material for sodium-ion batteries, and controlling the ratio of all elements, the present disclosure can achieve the formation of a perfect layered single-crystal structure of the cathode active material for sodium-ion batteries, with large particles, ultimately achieving the stability of the active material, and when used in sodium-ion batteries, it can significantly improve the cycling performance at high temperatures while ensuring high gram capacity.",
