Introduction to Faradaic Reactions in Electrochemical Systems

Understanding how chemical energy converts to electrical energy is at the heart of modern battery technology, fuel cells, and electrochemical sensors. To design or analyze these systems, you must first grasp the core physical chemistry governing reactions at the electrode interface. This text-only course provides a clear, step-by-step introduction to Faradaic reactions in dilute solutions, breaking down complex thermodynamic and kinetic concepts into accessible, readable lessons. What you'll learn: Understand the fundamental principles of Faradaic and non-Faradaic processes at the electrode interface; Apply dilute solution theory to model ion transport and concentration profiles; Master the Butler-Volmer equation and Tafel relationships to describe electrochemical kinetics; Analyze the role of mass transfer, diffusion, and migration in limiting reaction rates; Explore modern applications of these principles in contemporary battery chemistry and energy storage systems. You will start with foundational definitions of electrochemical potentials and interface thermodynamics, then progress through kinetic equations and mass transport models. This course is designed for engineering students, researchers, and professionals new to electrochemistry who want a solid theoretical foundation with no prior advanced prerequisites.
