Disclosed are a pre-lithiated lithium ion positive electrode material, a preparation method therefor and use thereof. The lithium ion positive electrode material has a chemical formula of LiO/[AMe]-LiAO, wherein A comprises M, and wherein M is at least one of Ni, Co, and Mn; and wherein Me is at least one of Ni, Mn, Al, Mg, Ti, Zr, Y, Mo, W, Na, Ce, Cr, Zn or Fe; and wherein 0<x<0.1. The material is co-doped with multiple elements, and these elements act synergistically to inhibit the irreversible phase change at a high voltage and improve the stability of the structure of a substrate. The spinel phase AMeOstructure contains the doping elements, which work together to improve the interfacial activity of the material and introduce more electrochemically active sites.
