What are the preparation methods of lithium manganate as cathode material for lithium batteries?

Preparation method of lithium manganate as cathode material for lithium battery 1. High temperature solid phase method. The basic process flow is: mixing → roasting → grinding → sieving → product. 2. Melt dipping method. It is a better method in the preparation of spinel lithium manganate by the solid phase method, which can obtain a positive electrode material with excellent electrochemical performance. However, due to complex operations and harsh conditions, it is not conducive to industrialization. 3. Microwave synthesis method. Its use in the synthesis of materials is clearly different from the traditional high-temperature solid-phase method. Using this method to prepare materials with excellent electrochemical properties can greatly shorten the synthesis reaction time. 4. Hydrothermal synthesis method. The lithium battery cathode material LiMn2O4 synthesized by the hydrothermal synthesis method has a stable crystal structure and uniform crystal state, so the synthesized material has excellent physical and electrochemical properties. 5. Co-precipitation method. The research stated that compared with solid-phase reaction, the lithium battery materials prepared by the co-precipitation method not only have higher electrochemical capacity and longer cycle life, but also have the advantages of simple process, simple operation, and fast reaction speed. 6. Sol-gel method. It is actually a branch of the co-precipitation method. The prepared LiMn2O4 has excellent physical and electrochemical properties, but it is not conducive to industrial processing due to problems such as high cost.
