Stefan Freunberger joins IST Austria in April 2020.

Freunberger Group

Materials Electrochemistry

Life uses electron transfer reactions to, e.g., store or retrieve energy and to produce useful chemicals and materials. The Freunberger group works on electrochemical materials sciences with broadly similar goals.

The group’s primary research interest lies in the fundamental science of electron and ion conducting and redox active materials (inorganic, organic and polymeric) as well as their mutual interactions in the working environment of electrochemical devices, particularly, energy storage devices such as rechargeable batteries. The results of this fundamental research find use in clean, efficient and sustainable energy sources. The foundations of the group’s research are (i) the synthesis of new conducting and redox active materials and a fundamental understanding of charge-carrier transport and electrochemical reactions, (ii) advanced physico‐chemical and spectroscopic investigations to understand the mutual behavior of the materials in their working environment as well as surface and interface processes, and (iii) the application in the electrochemical device that is a complex electrochemical reactor.
