In the process of PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC iron removal, especially when using magnetic iron removal, the cathode material may suffer some physical damage. When the cathode material passes through the strong magnetic field region, it may reunite or break up because of the magnetic field force. For some structurally fragile cathode materials, such as silicon-based cathode materials, this physical damage may change their particle size and shape, which in turn will affect their electrochemical properties.
Silicon-based anode materials are more and more widely used in lithium-ion batteries, which itself has the advantage of high specific capacity, but the integrity of the particle structure is crucial to its performance. If physical damage is caused in the process of PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC iron removal, it may lead to accelerated battery capacity decay, decreased cycle performance and other problems.
In the past, the negative removal of PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC mainly used chemical methods, but this method has some drawbacks. In the process of chemical iron removal, acid treatment needs to be removed, which will cause a large number of acidic wastewater and cause harm to the ecological environment.
