| titleOfInvention | A kind of preparation method of lithium nickel cobalt manganate |
| abstract | The invention discloses a preparation method of nickel cobalt lithium manganate. First, an intermediate product is formed under microwave conditions, and the intermediate product is ball-milled under the action of auxiliary agents absolute ethanol and ethylene glycol, and is changed by the action of mechanical alloying. The surface characteristics and morphology of the intermediate product particles, and then the black intermediate product is mixed with lithium salt, nickel salt, cobalt salt urea and hexamethylene tetramine, which is used to control the morphology, to form a mixed solution, and the precursor is obtained by reaction. After calcination That is, sea urchin-shaped nickel cobalt lithium manganate is obtained, the diameter of which is between 2-5 μm. The nickel cobalt lithium manganate prepared by the invention has stable manganese valence state, sea urchin-like appearance, controllable composition and easy adjustment. The nickel-cobalt lithium manganate obtained by the invention is used as the positive electrode material of the lithium battery, and the nickel and cobalt doping overcomes the shortcomings of the lithium manganate, improves its electrical properties, has the characteristics of high capacity and low attenuation, and has broad application prospects. |
