Scope
This document specifies the method for determining the magnetic particles in lithium battery materials. It describes the principle, reagents, instruments, testing steps, result analysis, and content of the test report for determining the number and size of metallic magnetic particles in lithium battery materials using an optical microscope with a polarizer. This document is applicable to lithium salts, cathode materials (including precursors), and anode materials. Other materials can also be used as reference.
