![]() ![]() A partial list of possible elements includes: Typically, several cell elements and cell characteristics contribute to the system's EIS spectrum. In EIS, you measure an electrochemical cell's complex impedance over a wide range of AC frequencies. It intentionally avoids most of the complex math associated with EIS data analysis. It should provide even a novice with the basic approach for converting an EIS spectrum into meaningful insights into the physical processes in his electrochemical cell. This Note is a practical discussion of the most common method for EIS data analysis. For the most part, information in that Application Note will not be repeated here. See the Basics of EIS application note for a comprehensive introduction to EIS. Electrochemical Impedance Spectroscopy (EIS) is a very powerful tool for the analysis of complex electrochemical systems.
