Young Investigator Group NEW E²
The research activities within the NEW E2 group focus amongst others on the development and characterization of alternative anode materials for lithium-ion batteries, which reversibly host lithium ions, for instance, by a combination of alloying and conversion – so called conversion/alloying materials. The target is to develop materials offering a synergetic combination of these two mechanisms, by this, enabling the respective advantages and, thus, overcoming the intrinsic drawbacks of each single mechanism. Specifically, such a combination allows for substantially reduced volume changes while simultaneously offering enhanced energy and power densities along with more efficient energy storage. This work has recently been extended also to the realization of completely new charge storage mechanisms involving the reversible insertion of various cations into well-maintained crystalline host structures. Another research field within the group is the development of organic (polymer-based) batteries, aiming for cell chemistries that are independent of (potentially) critical elements.
To achieve these goals, the group synthesizes and comprehensively investigates new and optimized materials via a series of electrochemical methods combined with a variety of in situ/operando characterization techniques, targeting the comprehension of the underlying reaction and charge transport mechanisms and, thus, enabling the development of new materials for the realization of high-performance, next generation secondary batteries.
