Introduction to Linear Sweep Voltammetry in Electrochemical Systems

Understanding how electrochemical systems behave under dynamic electrical potential is key to developing modern batteries, fuel cells, and sensors. Linear sweep voltammetry serves as a foundational diagnostic technique to reveal the kinetics and transport properties of these energy systems. This course guides you from the core physical principles to the practical interpretation of voltammetric data. You will transition from a basic understanding of electrochemical interfaces to confidently analyzing real-world current-potential curves. Through clear explanations and practical calculation exercises, you will learn how to extract kinetic parameters and diffusion coefficients directly from experimental data. What you'll learn: - Understand the foundational thermodynamics and kinetics of electrochemical reactions - Analyze how linear potential sweeps affect concentration profiles near the electrode - Calculate diffusion coefficients and transfer coefficients using standard electrochemical equations - Interpret voltammetric peak currents and peak potentials under different experimental conditions - Apply voltammetry concepts to modern energy storage systems like batteries and fuel cells - Recognize common experimental distortions, including ohmic drop and capacitive charging currents This course begins with essential terminology, covering the structure of the electrochemical double layer and basic charge-transfer theory, before progressing to mass transport and transient measurements. You will explore step-by-step derivations and practical data analysis scenarios to solidify your understanding. This course is designed for beginners, engineering students, and researchers new to electrochemistry, requiring no prior laboratory experience.
