The physical and chemical properties of tin-based cathode materials differ from those of carbon and silicon-based materials. In terms of PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC iron removal sieve, the method of density screening is limited because of the large density of tin-based materials and the relatively small difference in density with iron impurities. Lithium titanate has a special crystal structure and chemical properties.
Moreover, the tin-based materials may form some alloy phases during the processing process, and the iron impurities may exist in the form of an alloy, which increases the difficulty of iron removal. Special PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC iron removal methods are required, such as the difference in magnetic or chemical activity between tin-based materials and iron impurities. In the process of iron removal sieve, the influence of its crystal structure on iron removal should be considered.
Iron impurities may enter the crystal defect position and are difficult to remove by conventional iron removal methods. At the same time, the hardness of lithium titanate is higher, and the wear of the screen in the screening process is larger, so it is necessary to choose the wear-resistant screen material. Compared with other cathode materials, the PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC iron removal sieve of lithium titanate needs to be specially formulated according to its special structure and properties.
