Abstract

Disclosed are a cathode material for lithium ion batteries, a preparation method therefor, and use thereof, which relate to the technical field of lithium ion batteries. The ability of a polycrystalline cathode material to resist the generation of internal cracks during cycle is evaluated by anti-cracking strength. By providing a cathode material, which has an anti-cracking strength that satisfies a specific range, and a high-strength crystals and grain boundaries, so that the structural stability of the material can be improved, and the diffusion of the internal cracks to the interface can be effectively inhibited, thereby improving the cycle stability and lifetime of the material.
