Outline
In order to improve quality and performance of battery material, and address the battery safety issue, the contents of nickel, cobalt and manganese elements in the cathode materials of ternary lithium batteries are accurately determined by Inductively Coupled Plasma-Optical Emission Spectroscopy (ICP-OES), and the uncertainty in the measurement process is systematically evaluated according to the standard of JJF 1059.1—2012 “Evaluation and Representation of Measurement Uncertainty”. The uncertainty factors that may be introduced in each part of the test are deeply analyzed, and these uncertainties are carefully quantified and calculated. When the nickel content of the sample is 5.521 μg/mL, the extended uncertainty is U95(Ni)=0.013 1 mg/kg. When the content of cobalt is 3.566 μg/mL, the extended uncertainty is U95(Co)=0.011 8 mg/kg; when the manganese content is 2.102 μg/mL, the extended uncertainty is U95(Mn)=0.013 1 mg/kg. Finally, the synthetic uncertainty of nickel is u(Ni)=0.006 6 mg/kg, the extended uncertainty of cobalt is u(Co)=0.005 9 mg/kg, and the extended uncertainty of manganese is u(Mn)=0.006 5 mg/kg.
