Abstract
Electrochemical impedance spectroscopy measurements were performed to capture the physically meaningfulparameters of commercially available 18650 cylindrical and 2032 coin cells by using the equivalent circuit model. Theimpedance response of the batteries was systematically investigated and discussed. A detailed analysis was achievedproviding a determination of influential factors on the equivalent circuit parameters. The results suggested that the celltype tested here influenced the equivalent circuit elements profoundly. Taguchi analysis indicated that state-of-chargehad the highest effect on the cathodic constant-phase-element exponent. The results contribute to full electrochemicalanalysis that is required for battery characterization.
