(LiNiMnCoO2) and LiFePO4 (LiFePO4) etc..In recent years, since people are to anode material for lithium-ion batteries structure and property
What can be studied is more and more comprehensive, more and more deep, finds to contain magnetic metal impurity in anode material for lithium-ion batteries, these magnetic
Property substance presence, can not only reduce the specific capacity and energy density of material, but also the dissolution of some magnetic impurities is in the electrolytic solution,
A series of side reactions occur, reduce the service life, consistency and security performance of battery.It is magnetic in anode material for lithium-ion batteries
Substance also has direct influence on self discharge, and magnetisable material content is directly proportional to battery self discharge rate, i.e. magnetisable material content
The self-discharge rate of higher positive electrode, the battery of composition is bigger.
Therefore, the LiMn2O4 as one of the main positive electrode of lithium ion battery, magnetic metal impurity is mainly by band in EMD
Enter, the magnetisable material for how being precisely separating/collecting in EMD product, to detect the content of magnetisable material in EMD product to stabilization
Lithium cell anode material lithium manganate quality and raising performance of lithium ion battery have great importance.
