The present invention discloses a lithium-rich positive electrode material, a lithium battery positive electrode, and a lithium battery. The lithium-rich positive electrode material has a coating structure, where a general structural formula of a core of the coating structure is as follows: z[xLi2MO3·(1−x)LiMeO2]·(1−z)Li1+dMy2−dO, where in the formula, 0<x<1, 0<z<1, and 0<d<⅓; M is at least one of Mn, Ti, Zr, and Cr, Me is at least one of Mn, Co, Ni, Ti, Cr, V, Fe, Al, Mg, and Zr, and My is at least one of Mn, Ni, and Co; and a coating layer of the coating structure is a compound whose general formula is MmMz, where in the formula, Mm is at least one of Zn, Ti, Zr, and Al, and Mz is O or F. The lithium battery positive electrode and the lithium battery both include the lithium-rich positive electrode material. |
