Summary: | The invention discloses a preparation method of a high-performance coated positive electrode material. The preparation method includes the steps: uniformly mixing a manganese source, a nickel source and a metallic compound under a liquid-phase condition, and drying mixture to obtain a composite metal doped nickel manganese oxide; adding a lithium source and an organic carbon source to uniformly mix mixture, and roasting the mixture at high temperature to obtain a composite doped nickel manganese lithium material; adding the nickel source to treat mixture to obtain the high-performance coated positive electrode material. By the aid of a drying process, side reaction is avoided in the generating process of a lithium nickel manganese oxide, the organic carbon source is added, local temperature rapidly rises in the combustion process of the organic carbon, growth of a crystal is facilitated, energy consumption can be reduced, a trace carbon layer can be generated on the surface of the crystal, conductivity is imp |
