Introduction to Porous Electrodes in Electrochemical Systems

Porous electrodes are the heart of modern electrochemical energy storage and conversion devices, yet understanding how transport and reaction kinetics interact within these complex structures can be challenging. This text-only course provides a clear, step-by-step guide to the fundamental principles governing porous electrodes. You will transition from basic electrochemical concepts to analyzing and modeling real-world energy systems. What you'll learn: Understand the core physics of charge transfer and mass transport in porous media; Apply Newman's porous electrode theory to model battery and fuel cell performance; Analyze the relationship between pore structure, tortuosity, and effective conductivity; Practice calculating concentration overpotentials and ohmic losses in liquid electrolytes; Evaluate modern diagnostic techniques and degradation mechanisms in electrochemical systems. This course begins with essential definitions of electrochemical interfaces and transport phenomena, then guides you through mathematical modeling of porous structures, and concludes with practical design considerations for high-performance energy devices. This course is designed for engineering students, researchers, and technical professionals new to electrochemistry who want a solid foundation in electrode modeling without needing prior advanced coursework.
