  • Positive electrode material for lithium ion battery and preparation method therefor, and lithium ion battery
    Patent number: 11837722
    Abstract: A positive electrode material for a lithium ion battery and a preparation method therefor, and a lithium ion battery, relating to the technical field of secondary batteries. The positive electrode material comprises a high-nickel multi-element positive electrode material, the high-nickel multi-element positive electrode material is formed by agglomerating multiple primary grains, and the primary grains are distributed in a divergent shape along the diameter direction of the high-nickel multi-element positive electrode material, the aspect ratio L/R of the primary grains in the positive electrode material is greater than or equal to 3, and the radial distribution ratio of the primary grains in the positive electrode material is greater than or equal to 60%. The lithium ion battery containing the positive electrode material has high capacity and greatly improved particle strength.
