Testing of a Prototype Device Using Electrochemical Impedance Spectroscopy (EIS) Method

This paper deals with the electrochemical processes in lithium-ion batteries. To characterize the different electrochemical processes a method called electrochemical impedance spectroscopy (EIS) is used. The devices which perform EIS analysis are spread in all electrochemical laboratories but are expensive and their operation need certain level of knowledge and experience. This work is aiming to provide low-cost, user friendly device for EIS analysis The prototype of experimental device which utilize EIS method to characterize electrochemical parameters of cell is described. The prototype EIS device is tested and obtained results are compared with reference unit.
