Lithium ion battery positive electrode material and preparation method thereof

The invention relates to the technical field of lithium ion battery positive electrode materials and provides a lithium ion battery positive electrode material and a preparation method thereof. The Lithium ion battery positive electrode material comprises a magnesium source, a phosphorus source, a lithium source, an active material, an adhesive, additives and functional materials. By adding of thespecial additives and the functional materials, the lithium ion battery positive electrode material has advantages that a lithium ion battery positive electrode material manufacturing process is substantially shortened, mixing and ball milling time is 2-5h, positive electrode preparation efficiency is remarkably improved due to short mixing and ball milling time while lithium ion battery performances can be greatly improved, volume expansion of the electrode material in a charging and discharging process can be effectively improved, and coulomb efficiency and cycle stability of batteries areimproved. 本发明提供种锂离子电池正极材料及
