Welcome to the Freunberger laboratory website!
Our primary research interest lies in the fundamental science of electron and ion conducting and redox active materials (inorganic, organic and polymeric) and their mutual interactions in the working environment of electrochemical devices. Particularly materials science related to electrochemical energy storage devices such as rechargeable batteries. This field has expanded greatly due to the increasing need for clean and efficient mobile energy sources. The foundations of our research are (i) synthesis of new conducting and redox active materials and fundamental understanding of charge carrier transport and electrochemical reactions, (ii) advanced physical‐chemical and spectroscopic investigations to understand the mutual behaviour of the materials in the working environment and the surface and interface processes, and (iii) the application in the electrochemical device that is a complex electrochemical reactor.
