Materials for electrochemical devices
This course is part of the programme:
Materials (Third Level)
Objectives and competences
The main objective of the course is to give students theoretical and practical knowledge in the field of electrochemical conversion and storage of energy. Understanding electrochemistry is the basis for understanding electrocatalysis and batteries. The general understanding of low-carbon technologies in the context of sustainable development will be emphasized. The discussed topics are complemented by a number of practical examples and excursion. Students will prepare a seminar on a chosen subject within the scope of the course.
With the acquired knowledge, students will have an insight into the sustainable technologies of the future. This is useful both for basic research, for engineers, and for general education.
Content (Syllabus outline)
- Basics of electrochemistry
- Basics of electrocatalysis
- Principles of the operation of different types of electrochemical reactors
- Operation of fuel cells and electrolyzers with a proton exchange membrane (PEM)
- Synthesis of electrocatalysts
- Stability and activity of electrocatalysts
- Materials for electrochemical sensors
- Foundations of hydrogen economy
- Fuel cell vehicles and other usages
- Principles of operation of advanced battery systems
- Selected battery applications and outlook for their future development (pros and cons)
- Experimental techniques for the characterization of the materials used for conversion and storage of energy and their performance (potentiostat, electron microscopy, X-ray powder diffraction, ...)
- Introduction of the most important global research groups and industry
- Presentation of important global recent achievements and trends in the last year
- Tour of the laboratories at the National Institute of Chemistry
Intended learning outcomes
Knowledge and Understanding:
Students will be introduced to the principles and functioning of various electrochemical energy conversion and storage systems.
Physical and chemical phenomena within the electrochemical reactors such as the fuel cell and the battery will be explained in detail.
Students will be able to assess what materials are being used for these purposes. They will be able to choose the appropriate characterization techniques for an in-depth study of these materials, and at the same time to choose the right materials for the construction of energy conversion and storage devices.
They will learn how to assess the correct working conditions for certain applications of these devices.
The acquired knowledge will serve them for independent work in laboratories or industrial plants.

Assoc. prof. dr. Nejc Hodnik (h=15) is heading an Electrocatalysis group at Department of Catalysis in Chemical Engineering at National Institute of Chemistry, Ljubljana, Slovenia. He obtained his PhD from the Faculty of Chemistry in Chemical Engineering at the University of Ljubljana. During his doctorate, he was employed as a young researcher at the National Institute of Chemistry under the mentorship of dr. Stanko Hocevar, who led the research on the topic of fuel cells. In 2014 he went to Düsseldorf, Germany, at the Max-Planck Institute to join prof. dr. Karl Mayrhofer group with prestigious individual Marie-Curie Scholarship (now Marie Skłodowska-Curie). In 2016, he returned to Slovenia and started working at the Department of Catalysis in Chemical Engineering at the National Institute of Chemistry. Among other projects, he obtained a postdoctoral project from the Slovenian research agency (ARRS) in and after that the ARRS supplementary ERC project. In 2019, he was named adjunct (associate) professor at the University of Nova Gorica, where he teaches in the doctoral program Materials (Level 3). His bibliography contains more than 48 scientific papers published in international peer-review journals, more than 10 invited lectures and one international patent and three patent international applications. In 2019, he was awarded a European Research Council (ERC) Starting Grant.
