Introduction to Electrochemical Energy Storage Systems

As the world transitions to renewable energy, understanding how we store electricity chemically is one of the most critical engineering challenges of our time. This course provides a clear, structured path to mastering the fundamental chemical and thermodynamic principles that govern electrochemical devices. You will transition from understanding basic molecular interactions to analyzing complex energy storage systems used in modern vehicles and grid infrastructure. By reading this text-only course, you will build a solid foundation in the transport phenomena, thermodynamics, and kinetics that dictate how batteries and fuel cells operate under real-world conditions. What you'll learn: - Understand the core thermodynamic principles of electrochemical cells, including cell potential and Gibbs free energy. - Analyze charge transfer kinetics and transport phenomena using the Butler-Volmer equation and Fick's laws. - Evaluate the mechanisms, advantages, and degradation pathways of lithium-ion and next-generation battery chemistries. - Compare the operating principles and efficiency limits of fuel cells and electrochemical supercapacitors. - Apply mathematical modeling concepts to predict battery performance and state-of-charge under varying loads. The course begins with foundational definitions, electrochemistry basics, and governing equations before moving into detailed analyses of specific storage technologies and degradation mechanisms. It concludes with an overview of modern battery management systems and safety considerations. This course is designed for engineering students, researchers, and professionals looking to enter the clean energy sector. No prior advanced electrochemistry experience is required, though a basic background in general chemistry and physics is helpful.
