At present, the lithium ion battery has wide application in the fields of 3C digital products, power automobiles, energy storage equipment and the like. The lithium ion battery mainly comprises a positive electrode material, a negative electrode material, a diaphragm, electrolyte and the like. Among them, the cost of the positive electrode material accounts for the highest proportion of the total battery cost. The traditional anode material comprises ternary anode materials, lithium iron phosphate, lithium-rich manganese-based anode materials and other anode materials. In the preparation process of the various lithium ion battery anode materials, a high-temperature calcination process is carried out. During the calcination, the atmosphere, temperature, etc. need to be controlled. The calcination needs to be performed under the air condition for materials such as ternary cathode materials, lithium-rich manganese-based cathode materials, lithium manganate and the like. Whether the precursors can be contacted with enough oxygen or not in the calcining process plays an important role in the uniformity of the cathode material obtained by high-temperature calcination.
