Abstract: The present invention provides a single-crystal high-nickel positive electrode material and a preparation method therefor and an application thereof. The preparation method comprises the following steps: (1) mixing a precursor, a lithium source, and a nano oxide, and performing primary sintering treatment in an oxygen-containing atmosphere to obtain a primary sintered material; and (2) mixing the primary sintered material obtained in step (1) with a titanium source and a cobalt source, and performing secondary sintering treatment in an oxygen-containing atmosphere to obtain the single-crystal high-nickel positive electrode material. The present invention uses a Ti/Co co-coating method, the residual alkali amount of the prepared single-crystal high-nickel positive electrode material can be greatly reduced, and the capacity and the rate capability can also be kept at a high level, so that the technological process is reduced, and the cost is reduced.
