| titleOfInvention | Nickel cobalt lithium manganate ternary positive electrode material and preparation method thereof |
| abstract | The invention discloses a nickel cobalt lithium manganate ternary positive electrode material and a preparation method thereof, wherein the preparation method comprises the following steps: (1) mixing a lithium source, nickel cobalt manganese hydroxide and an M element compound, ball-milling, sintering and crushing to prepare a nickel cobalt lithium manganate ternary positive electrode material substrate; (2) mixing a nickel cobalt lithium manganate ternary positive electrode material matrix, a Co source and an N element compound, ball-milling, sintering and crushing to obtain a nickel cobalt lithium manganate ternary positive electrode material; the M element is one or more of Zr, Al, Ti, Mg, Sr, Nb, Y, W, B, Mo, Ce, Bi and In; the N element is selected from one or more of Zr, Al, Ti, B, Mo, Ce and In. The surface of the lithium ion battery anode material prepared by the invention has a coating layer, and simultaneously realizes the surface doping effect, and the coating layer is a cobalt-lithium oxide electrochemical active substance, so that the structural stability is improved, and the capacity loss caused by the conventional coating is avoided. |
