Abstract
The paper deals with the measurement of the cell impedance parameters during discharging of the Li-ion NCR18650B cell. Re (Z) and Im (Z) of the battery were measured by PEIS method. The results of the impedance changes during discharging and charging were plot to Nyquist diagrams. The important values namely Rs, Rsei, Rct, Csei, Qsei, Cdl, , and were found during discharging of the Li-ion cell with and without using CPE element.
