As we all know, positive electrode material is one of the key core materials of lithium-ion battery, whose performance directly affects the performance indicators of lithium-ion battery. Currently, positive electrode materials of lithium-ion battery have been marketed, including lithium cobaltate, lithium manganate and lithium iron phosphate. Self-discharge can cause fatal effects on lithium-ion batteries, PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC iron removal is to prevent the introduction of metal foreign matter from the source is particularly important.
The cathode MATERIAL is mixed with metal foreign body, which requires PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC for iron removal. If iron (Fe), copper (Cu), chromium (Cr), nickel (Ni), zinc (Zn), silver (Ag) and other metal impurities exist in the positive electrode material, the battery formation stage voltage reaches the REDOX potential of these metal elements, these metals will be oxidized at the positive electrode and then reduced to the negative electrode. When the metal elements at the negative electrode accumulate to a certain extent, The hard edges of the deposited metal puncture the diaphragm, causing the battery to self-discharge.
Raw materials are the direct source of metal foreign bodies in cathode materials, raw materials should be purchased for PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC iron removal, so that the content of metal foreign bodies to meet the requirements, after entering the factory should be strictly tested to ensure that its content in the specified range.
