AbstractIntroduction to electrochemistry from a physical chemistry point of view, focusing on thermodynamics and kinetics of electrochemical reactions and the engineering of electrochemical cells. The topics are of generic nature yet also discussed in the context of specific applications in industrial electrochemistry, energy storage and conversion, electroanalytical techniques, sensors and corrosion.
ObjectiveThe course establishes the fundamentals to understand and describe electrochemical reactions. The students are familiarized with key concepts and approaches in electrochemistry and selected aspects of materials science and engineering and how they are put to use in selected applications.
