The ability to obtain insight into fundamental mechanisms is becoming increasingly important for the development of new storage technologies and conversion systems. Therefore the understanding of electrochemical and catalytic reactions and ionic transport properties is a prerequisite to boost the performance of batteries, fuel cells and H2-generating systems.
The knowledge of the kinetics and mechanisms gained by investigation of the e.g. electrode processes is used for the development of novel electrolyte and electrode materials. In addition physico-chemical analysis of materials, components and functional interfaces with respect to the defect chemistry can help to get a fundamental understanding of (defect) structure/ function relation in electrochemical components.
