Introduction to Electrode Impedance and Electrochemical Systems

Understanding how charge moves across electrochemical interfaces is critical for designing better batteries, fuel cells, and sensors. This course introduces you to the core principles of electrode impedance, translating complex physical chemistry into clear, actionable engineering concepts. You will transition from learning foundational electrical definitions to analyzing real-world electrochemical systems. What you'll learn: Understand the physical principles of charge transfer, double-layer capacitance, and mass transport; Analyze electrochemical impedance spectroscopy data using equivalent circuit models; Interpret Nyquist and Bode plots to diagnose electrode performance; Apply impedance analysis to modern energy storage and conversion devices; Practice identifying common experimental artifacts and measurement limitations. You will start with essential electrochemical definitions, progress through the mathematical modeling of interfaces, and finish by reading and interpreting complex impedance spectra. Designed for beginners in chemical engineering, materials science, or electrochemistry, this course requires no prior experience with impedance spectroscopy. Start reading today to master the fundamentals of electrochemical interfaces.
