| titleOfInvention | Vanadium pentoxide-coated core-shell structure gradient nickel-cobalt-manganese positive electrode material and preparation method thereof |
| abstract | The vanadium pentoxide-coated core-shell structure gradient nickel-cobalt-manganese cathode material is prepared by coating a vanadium pentoxide coating layer on a core-shell structure gradient nickel-cobalt-manganese cathode material; having a chemical formula of V 2 O 5 @ LiNi x Co y Mn (1‑x‑y) O 2 Wherein x is more than or equal to 0.5 and less than or equal to 0.85, y is more than or equal to 0.05 and less than or equal to 0.4, and 1-x-y is more than or equal to 0; the core-shell structure gradient nickel-cobalt-manganese cathode material is prepared by sintering a core-shell structure gradient nickel-cobalt-manganese cathode material precursor mixed with lithium. The preparation method comprises the following steps: (1) aging, filtering, washing and drying the precursor of the positive electrode material; (2) adding a lithium source, grinding, pre-sintering and sintering; (3) mixing with a vanadium source in an alcohol solution, performing ultrasonic treatment, and performing heating reaction; (4) and (4) performing heat treatment in an oxygen-containing atmosphere to obtain the product. The battery assembled by the anode material has high discharge specific capacity and good cycle and rate performance; the method is simple, low in cost and suitable for industrial production. |
