KurzbeschreibungIntroduction to electrochemistry from a physical chemistry point of view, focusing on thermodynamics & kinetics of electrochemical reactions, and engineering aspects 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.
LernzielThe course establishes the fundamentals to understand and describe electrochemical reactions and phenomena related to these. 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.

- Chapter I - Redox reactions, Faraday’s laws;

- Chapter II - Equilibrium electrochemistry:
cells, galvanic and electrolytic cells, thermodynamic state functions, theoretical cell voltage, half-cell / electrode potential, hydrogen electrode, the electrochemical series, Nernst equation;

- Chapter III - Electrodes & interfaces:
