Content, Learning Outcome and Preconditions
Many energy conversion and storage processes are based on electrochemical devices. Among them batteries and fuel cells are certainly the most well-known; others include water electrolyzers and supercapacitors whose importance steadily increases. The lecture discusses the electrochemical fundamentals required in current research on electrochemical energy conversion. It covers thermodynamics and microscopic structures of the solid-liquid interface, the kinetics of charge transfer processes as well as transport processes in the electrolyte. The above aspects are discussed not only for macroscopic electrodes, but also for nanoelectrodes as well as microelectrode arrays and structured surfaces. In addition to the physical and electrochemical foundations, state-of-the-art methods for the investigation of the solid-liquid interface are introduced. These include cyclic voltammetry, impedance spectroscopy, scanning probe and spectroscopic methods.
After successful completion of the module the students are able to:
- understand and apply thermodynamics and kinetics at the solid-liquid interface
understand electrochemical processes in important energy conversion or storage processes (e.g., batteries, fuel cells, water splitting, supercapacitors, etc.)
- understand basic features of state-of-the-art investigation methods at solid-liquid interfaces, such as cyclic voltammetry, impedance measurements, scanning probe or spectroscopic methods
No preconditions in addition to the requirements for the Master’s program in Physics.

Learning and Teaching Methods
The teaching an learning content is presented, discussed, and explained in a structured and detailed manner. A comprehensive knowledge of the physical and chemical aspects of electrochemical interfaces is imparted. Universal methodic and physical concepts are highlighted by cross referencing between different topics. The students are involved in scientific discussions to stimulate their analytic thinking in physical problems. Regular attendance is, hence, highly recommended.
The presentation of the learning content is enhanced by examples and calculations. They are intended to deepen the students understanding of the course material. The students are welcome to discuss any problems with the teacher or the tutors.

Description of exams and course work
There will be an oral exam of 30 minutes duration. Therein the achievement of the competencies given in section learning outcome is tested exemplarily at least to the given cognition level using comprehension questions, reflection of simple formulas for the description of elementary relations, and sample calculations for order-of-magnitude estimates.
For example an assignment in the exam might be:
- Description of a interface between a solid and a liquid phase.
- Explanation of the potential distribution across an electrochemical interface.
- Describing and explaining the charge transfer process across an electrochemical interface.
Participation in the exercise classes is strongly recommended since the exercises prepare for the problems of the exam and rehearse the specific competencies.
The exam may be repeated at the end of the semester.
