From the perspective of the overall process requirements, the goal of the PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC iron removal screen is to reduce the content of iron impurities to a very low level to meet the high performance requirements of lithium batteries. In some high-end application scenarios, such as lithium batteries for electric vehicles, the performance and safety requirements of batteries are extremely high, which requires the iron impurity content in the negative electrode material after iron removal screening to be as close to zero as possible.
At the same time, PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC iron removal screening process also needs to take into account production efficiency and cost, and can not excessively increase production cost or reduce production efficiency because of the pursuit of iron removal effect. For example, the adoption of too complex or expensive iron removal equipment may increase costs, while too cumbersome screening steps may reduce production efficiency. Therefore, it is necessary to optimize the process, improve the production efficiency and reduce the cost under the premise of ensuring the effect of iron removal.
Moreover, low temperature may lead to changes in some physical properties of cathode materials, and the brittleness of the material increases, which may affect the physical operation in the process of PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC iron removal. When using physical methods such as filtration for iron removal, the brittleness of the material may lead to the crushing of the material, which will affect the effect of iron removal.
