Inhalt:

The module advanced electrochemistry provides a fundamental insight into electrochemical systems and discuss advanced electrochemical methods. Based on this knowledge, students will be able to understand electrochemical problems, suggest methods to solve them and understand the background of many practical electrochemical systems and applications, required for the understanding of electrochemical reactor technology. They will also get an insight into the fundamental research problems of modern electrochemistry. Practical electrochemical systems will be discussed that are either already of great economic importance or will become crucial in future applications. Students will gain knowledge on the most relevant applied electrochemical research topics, will have a clear view on the versatility of electrochemical devices and have an understanding of electrochemistry based energy systems and their potential. Several technologies of importance in energy conversion systems and the production of added-value chemicals like electrolysers, fuel cells, flow batteries, supercapacitors, chloralkali process, organic electrosynthesis, aluminum production, but also corrosion, metal deposition, ectroanalysis, electrochemical sensors, lithography galvoforming, semiconductors, information storage, bioelectrochemistry, photoelectrochemistry, conducting polymers, will be discussed.
