  • Publication number: 20250112234
    Abstract: The present application relates to the field of lithium-ion batteries and discloses a lithium-ion battery cathode material, a preparation method thereof, and a lithium-ion battery. A ratio of surface Ni3+ content of the cathode material to internal Ni3+ content of the cathode material is (0.95 to 1):1, and a content of disordering nickel in the cathode material is less than or equal to 3%. The lithium-ion battery cathode material has the similar surface Ni3+ content and internal Ni3+ content, and has a low content of disordering nickel, thereby avoiding the generation of a NiO passivation layer in the cathode material and reducing the phenomenon of loss of surface active lithium. The lithium-ion battery containing such a cathode material has improved capacity, rate capacity, and cycle performance.

    Abstract: The present disclosure relates to a positive electrode material and the preparation method therefor. The positive electrode material in accordance with the present disclosure is in a form of secondary particles having a core and a shell, wherein the core has a porosity greater than that of the shell. By forming larger particle voids in the cores of secondary particles, the present invention may reduce the stress concentration due to the volume deformation during the lithium ion intercalation/deintercalation, and improve the stability, rate performance, safety and cycle life of the material, which makes the material particularly suitable for lithium-ion batteries of high energy density.
