Abstract
Provided in the present disclosure are a cobalt-free high-nickel positive electrode material, a preparation method therefor and use thereof. The cobalt-free high-nickel positive electrode material comprises a cobalt-free high-nickel matrix material and a coating layer coated on the cobalt-free high-nickel matrix material, wherein a chemical formula of the cobalt-free high-nickel matrix material is LiNiMnO, where 0.2≤m≤0.8, 0.4≤x≤0.95, and 0.05≤y≤0.6; and the coating layer is TiBO, where 0.2≤z≤0.8. The cobalt-free high-nickel positive electrode material obtained by means of modification using the coating layer TiBOhas good acid resistance and wear resistance, high mechanical strength and excellent conductivity; and when the cobalt-free high-nickel positive electrode material is used for a lithium ion battery, the high-temperature cycling performance, capacity and initial efficiency of the lithium ion battery are greatly improved.
