  • Docentföreläsning

The Department of Chemistry - Ångström Laboratory hereby invites all interested to a docent lecture covering the subject chemistry with a focus on materials chemistry. The lecture will be given in English.

Chair: Prof. Daniel Brandell
Docentur board representative: Prof. Adolf Gogoll  

The lecture, which is a teaching test for those who apply to be admitted as a docent / associate professor, must be understandable by students and others with a knowledge at an undergraduate level of the subject, but may also be of interest to a wider audience. The lecture lasts 45 minutes, followed by questions and discussions, and will be given in English.

Astract

"Iron is one of the most abundant element in the earth’s crust and its early discovery played a central role in the development of a series of technologies for the human kind.

Today’s society faces a number of technological challenges and those concerning more sustainable uses of resources and materials to produce and harness energy are crucial for limiting global warming and pollution of our planet.

Rechargeable batteries are promising electrochemical devices that provide efficient storage of electricity in the form of chemical energy and represent a crucial link between the production of clean energy via renewable sources and its effective utilization at a required time.

Rechargeable batteries, however, are typically made of toxic, polluting and expensive materials (e.g. Pb, Cd, Ni, Co, etc.) which represent a threat to the environment. Hence, a large-scale deployment of rechargeable batteries in both mobile and stationary applications needs to look also into alternative materials and solutions that can mitigate this drawback. Iron and some of its compounds can constitute interesting candidates to address this issue, as they are abundant, non-toxic and inexpensive.

Some examples of possible uses of iron-based materials will be provided in this lecture, together with insights into some of their current limitations and challenges for the development of more sustainable rechargeable batteries."
