Foundations of Electrochemistry: Theory, Equations, and Energy Applications

Electrochemistry is the driving force behind modern energy storage, metal refining, and chemical sensors. Understanding how chemical reactions generate electricity—and vice versa—is essential for any aspiring chemist, engineer, or science student. This text-based course guides you from the fundamental definitions of redox reactions to the complex calculations of electrochemical thermodynamics. You will build a solid theoretical foundation and learn how to apply these principles to real-world technologies like batteries and fuel cells. What you'll learn: - Understand foundational concepts including oxidation states, redox reactions, and balancing half-reactions - Calculate cell potentials and free energy changes using the Nernst equation and thermodynamic principles - Analyze the differences between galvanic and electrolytic cells, including their commercial applications - Explore modern energy storage systems, including the chemistry behind lithium-ion batteries and fuel cells - Apply Faraday's laws of electrolysis to solve quantitative stoichiometry problems - Practice step-by-step calculations for conductivity, molar conductivity, and transport numbers. The course starts with essential terminology and the basics of electron transfer before moving into cell thermodynamics, kinetics, and practical applications in modern green energy. It is designed for science students, chemistry aspirants, and self-learners seeking a clear, structured introduction to electrochemistry without any advanced prerequisites.
