Remove iron from lithium iron phosphate

In the production process of graphite electrode, the principle of multistage iron removal of graphite is also widely used. In some medium-sized graphite electrode production enterprises, permanent magnet graphite PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC can remove large particle iron filings and some fine iron impurities in the raw material. This is of great significance to improving the charge and discharge performance and cycle life of lithium-ion batteries.


PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC

First, in the raw material treatment stage, the permanent magnet graphite PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC is used for primary iron removal. Some enterprises will also increase the three-level iron removal link, the use of high gradient magnetic separation machine to remove the graphite material for iron removal after the second iron removal, further improve the purity of graphite, to ensure that the final production of iron impurities in the graphite anode material is very low, to meet the requirements of high performance of lithium ion batteries.


what is magnetic separation in Feldspar?

By multistage PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC iron removal, the iron impurity content in graphite anode materials can be reduced to very low levels, and the iron impurity content can be controlled within a few parts per million. The high purity graphite anode material can reduce the internal resistance of the battery, improve the energy density and charge and discharge efficiency of the battery, and prolong the service life of the battery, and improve the safety of the battery.
