  "textContent": "The present disclosure relates to the technical field of lithium-ion batteries, and particularly, to a multi-element cathode material, a preparation method thereof, a positive electrode plate, and a lithium-ion battery. The multi-electrode material is composed of secondary particles agglomerated by primary particles. A ratio of a total cross-sectional area of the primary particles with more than 5 grain boundaries to a cross-sectional area of the secondary particles is greater than or equal to 3:4. A porosity on a cross-section of the secondary particles is less than or equal to 2%. A grain boundary is a contour line of an interface between the primary particles with the same structure but different orientations on the cross-section of the secondary particles and a length of the grain boundary is greater than or equal to 0.1 μm.",
