The types of cathode materials for sodium ion batteries include metal oxides, polyanions and organic compounds, etc. The layered transition metal oxide materials have attracted wide attention because of their advantages of high working voltage and capacity. At present, the widely used PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC preparation method has the following advantages:
The particle size, morphology and phase state of the material in the solid phase preparation process, the collision between the particles in the ball grinding process, and the materials prepared by PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC have good uniformity; the sol-gel process is relatively simple, the organic materials with short preparation cycle and saving, suitable for industrial production;
Although the co-precipitation method can obtain the cathode material with smooth surface, uniform particle size distribution and high vibration density by controlling the reaction conditions, the pH value can be accurately controlled during the preparation of precursor by PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC to ensure the uniform and complete precipitation of transition metals. At present, it is urgent to optimize the synthesis method to prepare cathode materials with stable electrochemical properties and good crystallization to replace lithium-ion battery materials.
