Abstract: Electrochemical impedance spectroscopy (EIS) is an important electrochemical measurement method. It is widely used in the field of electrochemistry, especially in lithium ion batteries, such as measuring the electrical conductivity, apparent chemical diffusion coefficient, growth and evolution of SEI, charge transfer and the mass transfer process. This paper mainly focused on the basic principle of electrochemical impedance spectroscopy (EIS), the testing methods, the matters needing attention and the equipment used in the electrochemical impedance measurement. Finally, the application of the electrochemical impedance spectroscopy in the lithium ion battery is introduced in a practical case.

Key words: electrochemical impedance spectroscopy, measurement, analysis methods, lithium batteries
