Introduction to Charge Transfer at Metal Electrodes

Electrochemical processes are at the heart of modern energy technology, driving everything from advanced batteries to fuel cells. Understanding how electrical charge moves across the interface between a metal electrode and an electrolyte is essential for designing efficient energy systems. This course provides a clear, structured introduction to the physical and chemical principles governing charge transfer at metal electrodes. You will transition from understanding basic interface structures to analyzing complex kinetic models, giving you the theoretical foundation needed for electrochemical engineering. What you will learn: Understand the structure of the electrochemical double layer at metal-electrolyte interfaces; Analyze the thermodynamics of electrode reactions and the origin of overpotential; Apply the Butler-Volmer equation to model charge transfer kinetics; Explore modern electrochemical systems, including battery electrodes and fuel cell catalysts; Practice evaluating reaction rates and energy losses using standard kinetic equations. The course begins with foundational concepts of electrochemistry and interface physics before moving into mathematical models of charge transfer and real-world application scenarios. This course is designed for beginners in chemical engineering, materials science, or chemistry who want a solid theoretical starting point in electrochemistry, with no prior advanced kinetics required.
