A Short Course on Electrochemical Impedance Spectroscopy: Theory, Applications, and Laboratory Instruction

Now in its 37th year, this 4 Day course is the same course as the previous 4 ½ Day (5 Day) course. The time and depth allocated to all course topics and experiments is the same (or more) compared to the 4 ½ day course. The change to 4 days was made to be more efficient with everyone’s time. If you are interested in the 4 Day Course, please register. Remember, your registration in the course is not official until course payment has been received. If you have additional colleagues in your company or institution that are also interested in increasing their knowledge and skills in EIS, an onsite course that is customized in content and duration to your group’s needs may be a more practical and economic consideration. If you are interested in a customized EIS course at your site, please contact Prof. Ray Taylor at srt5387@gmail.com.

Course Overview

Impedance spectroscopy is an extremely powerful non-destructive investigative technique that can obtain essential information about interfacial and bulk material parameters through the use of low energy, time varying electrical excitation. When applied to an electrochemical system, electrochemical impedance spectroscopy (EIS) can provide information on reaction parameters, corrosion rates, oxide characteristics and integrity, surface porosity, coating integrity, mass transport, and many other electrode/interface characteristics. EIS is one of the most powerful methods available in electrochemistry today and is utilized in research and development in essentially every technical sector, e.g., transportation and infrastructure, batteries and fuel cells, medicine, among many others. However, effective utilization of this method has been hindered by the lack of a comprehensive and cohesive explanation of the theory, measurement, and analysis techniques. This course on EIS has been developed to fill this void.

Now in its 37th year, this short course was first taught in 1988 in Charlottesville, Virginia. It was taught in Houston beginning in 2007, in Seattle in 2022, and now has the fortune of being held in the historic and technologically rich city of Philadelphia, Pennsylvania.
