The Fleischmann Lab develops novel electrode materials for electrochemical energy storage devices based on ion intercalation. We focus on overcoming current limitations regarding fast-charging and lifetime of batteries, as well as substituting critical raw materials by more abundant elements.
Soft chemistry routes are developed to tune the nanoconfinement environment of the interlayer space within layered and two-dimensional materials. These materials serve as host structures for electrochemical ion intercalation reactions and are put to work as electrodes in electrochemical cells, evaluating their charge storage capacity, rate handling, ionic mobility and impedance.
Understanding of the emerging charge storage mechanisms requires the use of advanced ex situ and operando characterization. For this purpose, our lab establishes methods including cryogenic electron microscopy, X-ray absorption spectroscopy, electrochemical quartz-crystal microbalance, and electrochemical dilatometry.
