Scope
This standard specifies the principles, measurement environment conditions, reagents and instruments, testing steps, result analysis and calculation, and test report content for determining the content of magnetic substances (the total content of iron, cobalt, chromium, nickel, and zinc) in nano-negative electrode materials used in lithium-ion batteries by inductively coupled plasma optical emission spectrometry (ICPOES). This standard is applicable to the determination of magnetic substance content (the total content of iron, cobalt, chromium, nickel, and zinc) ranging from 0.02×10-6 to 20×10-6 in mass fraction.
