Master's thesis – In-situ X-ray diffraction of cathode materials for sustainable sodium-ion batteries

Research for a society in change: This is our drive at the Jülich Research Centre. As a member of the Helmholtz Association, we are presenting great social challenges of our time and exploring options for the digi­tali­sated society, a climate-saving energy system and related services. Work together with some 7,600 colleagues: in one of the largest research centres in Europe and shape the change with us! In the Institute of Energy Technologies – Basics of Electrochemistry (IET-1) we are researching highly topical topics about the energy transition and structural change. For example, we focus on the battery of the future and explore new battery concepts. How to make the greenhouse gas carbon dioxide (CO2) from the climate killer a raw material of the future is another exciting topic that we are dealing with. The aim of the research and development work is cost-effective batteries, fuel cells and electrolyzers with improved energy and power density, longer service life and maximum safety!

We offer at the next possible time Master thesis – In-situ X-ray diffusion fraction of cathode materials for sustainable sodium ion batteries

Na-ion batteries are a chance-rich alternative to Li-ion batteries for a turn to environmentally friendly and resource-saving materials and can simultaneously represent a solution strategy for growing energy demand. The research area of the Na batteries is an emerging theme, in particular in the development of sustainable cathode materials. Within the scope of the master thesis, sustainable cathode materials which have been developed are to be investigated with in situ X-ray diffraction in terms of their phase stability. Your tasks in detail: Literature research into layered transition metal oxides Processing into the cathode processing Input into X-ray diffraction Conducting electrochemical measurements in half cells Evaluation of diffractograms and electrochemical measurements

Good studies in the master's degree in chemistry, chemical engineering, physics, materials sciences, mineralogy / crystallography or a similar subject Knowledge of X-ray diffraction and electrochemistry Interest in electrochemistry and batteries Enthusiasm for experimental work in the laboratory High level of self-employment and structured working Good English in Word and Writing, German knowledge of advantage

We work on highly topical socially relevant topics and offer you the opportunity to actively shape change! It expects a diverse range: Sensual tasks: Their thesis addresses a future-oriented, socially relevant topic with immediate practical relevance in an international environment. Scientific environment: You expect excellent scientific equipment, modern technologies and qualified support from experienced colleagues. Flexibility: Flexible working time design makes it easier for you to work together. Health and well-being: Your health is at our heart. It offers extensive occupational health management with a variety of offers – e.g. through beach volleyball court, running groups, yoga courses and much more. In addition, our medical service as well as an experienced team of social counselling are on site. Fair remuneration: Your final work will be appropriately rewarded with us. In addition to exciting tasks and a collegial team, we offer you a lot more: go.fzj.de/Benefits. .
