Abstract: The present invention relates to the technical field of lithium-ion batteries, and discloses a precursor of a lithium-containing oxide cathode material, a lithium-containing oxide cathode material, a preparation method and use thereof, and a positive electrode plate and use thereof. The cathode material has a compressive index Δλ(P100) satisfying Δλ(P100)≥60%+(y/x)×5%, where y/x is a molar ratio of Mn/Ni in the cathode material. The lithium-containing oxide cathode material has high compressive strength and stability, only a small degree of fracture occurs under high pressure during a preparation process of the electrode plate, and it can be continuously subjected to lithium ion deintercalation/deintercalation reactions without serious rupture.
