Are there any magnetic materials in lithium ion batteries?
Except for tiny nickel lugs, there is none in the core.There is cobalt in the core, but not cobalt. It should not be considered as a magnetic material.As for the outer packing of the battery, it's hard to say, it's made of steel shell.
The steel shell and nickel electrode are ferromagnetic materials; lithium cobalt and lithium niobate are weak magnetic materials, and 12000 Gauss will be magnetized;
These 4 kinds of magnetic material content should be strictly controlled, generally below 50ppm bar
The anode material is to detect magnetic material (Fe Cr what), a total of 4 kinds of magnetic material
