GB/T 41704-2022 Test methods of cathode materials for lithium ion battery—Determination of magnetic impurities content and residual alkali content
Abstract
This document specifies the determination methods for the content of magnetic foreign matter and residual alkali in cathode materials of lithium-ion batteries.
This document is applicable to the determination of the content of magnetic foreign matter and residual alkali in cathode materials of lithium-ion batteries. The determination range of magnetic foreign matter content is ≥1 μg/kg, and the determination range of residual alkali content (mass fraction) is 0.001% to 2.500%.
