  "textContent": "The present application relates to the technical field of lithium-ion battery and discloses a multi-element cathode material and, a preparation method thereof, and a lithium-ion battery. A surface of the multi-element cathode material includes a dot-like coating and/or an island-like coating. A particle diameter Dwith 1% cumulative particle size distribution of the multi-element cathode material is greater than or equal to 0.7 μm. An arithmetic average roughness Ra, measured with a three-dimensional scanning electron microscope, of the coating of the multi-element cathode material satisfies 20 nm≤Ra≤200 nm. A coverage Q of the dot-like coating and/or the island-like coating of the multi-element cathode material satisfies 3%≤Q≤30%. The surface of the multi-element cathode material contains the dot-like coating and/or the island-like coating, and the coating has specific arithmetic average roughness and coverage. Moreover, the multi-element cathode material has a relatively great particle size distribution D.",
