The present invention provides a preparation method and application of a high-performance nickel 55-type modified nickel cobalt lithium manganate material, and relates to the field of lithium-ion battery materials. According to the preparation method, a polymer-coated nano precursor containing a silicon dioxide template is prepared by an electrostatic spinning method, and effective embedding and attachment sites can be effectively provided for subsequent nickel plating after air sintering; and the silicon dioxide template is removed after nickel plating, mesopores are generated and distributed on the precursor in situ, the mesopores provide channels for subsequent molten lithium to penetrate through the interior of the precursor material, and the finally prepared material has a better ion and electron conduction structure compared with a traditional particle material. Also disclosed in the present invention is a material prepared by the method. The material has uniform dispersion morphology ...

The present invention relates to the technical field of lithium-ion battery materials. Disclosed are a lithium nickel manganese cobalt oxide positive electrode material of a high-performance power battery and a preparation method therefor. In the preparation method for the lithium nickel manganese cobalt oxide positive electrode material of the present invention, a melt mixing method, a spray-drying method, a sol-gel method, and a high-temperature solid-phase method are combined to cause precursor components to be uniformly mixed to obtain a product having a uniform particle size, excellent electrochemical performance, and high cycle stability. The method has simple operation steps, low cost of raw materials, short time consumed, and high production efficiency, and can realize large-scale industrial production. The present invention also provides a lithium nickel manganese cobalt oxide positive electrode material prepared by the method, which has high charge-discharge specific capacity, ...
