An offset angle of a (104) diffraction peak of the cathode active material is α, n is the number of charging cycles of a battery including the cathode active material, where n is an integer; m % is a percentage of a charging capacity to a total capacity of the battery at a n-th charging cycle of the battery; αis a 2θ value corresponding to the (104) diffraction peak in an XRD diffraction spectrum of the cathode active material when the percentage of the charging capacity to the total capacity of the battery is m % at the n-th charging cycle of the battery; αsatisfies: α−α≤0.250°; and α−α≤1.500°.",
