Introduction to Electrochemical Energy Systems and Symmetric Trap Models

Electrochemical energy systems are at the heart of modern battery technology, fuel cells, and sustainable engineering. To truly master how energy is stored and released, you must understand how molecules and ions overcome physical energy barriers, often modeled as escaping a symmetric energy trap. This text-only course guides you through the fundamental chemical engineering principles that govern these microscopic processes. You will transition from theoretical thermodynamics to practical calculations of ion transport and reaction kinetics. Through clear explanations, you will learn how to model energy states, calculate activation barriers, and apply these concepts to modern battery chemistry. What you will learn: Understand the core concepts of electrochemical potential and Gibbs free energy; Analyze the symmetric trap model to explain how ions escape energy barriers; Apply the Butler-Volmer equation and Tafel kinetics to real-world electrochemical systems; Calculate ion transport rates and diffusion coefficients in structured materials; Model energy storage efficiency and degradation patterns in modern battery cells. The course begins with foundational definitions of electrochemistry and thermodynamics before moving into advanced kinetics, transport phenomena, and practical energy storage applications. This course is designed for chemistry students, chemical engineers, and energy technology enthusiasts who have a basic background in general chemistry and algebra.
