PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC Iron removal sieve is a key link in the production process of lithium battery cathode materials. Generally speaking, it is in the middle or late stage of material processing, after the material has been broken, mixing and other operations. This is because in these early operation process, the wear of the equipment, raw materials into the introduction may introduce iron impurities. If the iron impurities cannot be effectively removed, it will have a serious impact on the performance of lithium batteries.
Iron impurities will affect the charge and discharge performance of the battery, resulting in the reduction of the battery capacity, shortened cycle life, and may also cause a short circuit inside the battery, reduce the safety of the battery. Therefore, the quality of PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC iron removal screening skills is directly related to the overall quality and performance of lithium batteries
At low temperature environment, the ion conductivity of the electrolyte will decrease, which will affect the embedding and detachment process of lithium ions in the electrode material. In the process of PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC iron removal, if the iron removal is based on the electrochemical mechanism, the rate of electrode reaction at low temperature will be reduced, and the efficiency of iron removal will be also reduced.
