[0002] In the production of lithium battery positive electrode material, it needs to go through the process of kiln sintering. Through high-temperature sintering, the crystal structure of the positive electrode material can be formed and stabilized, and the ideal crystal form and lattice parameters can be obtained. This is crucial for the electrochemical performance of the material. The sintering process can promote the chemical reaction inside the material, allowing the components to mix thoroughly and distribute uniformly, thereby improving the conductivity, ion diffusion rate and structural stability of the material.
