Alternative Battery Concepts

With the help of high-resolution analytics, we are working on the optimisation of rechargeable zinc-manganese dioxide batteries.

Lithium Ion Batteries:

We aim to investigate inner and outer surfaces and interfaces of cathode and anode active materials in lithium ion batteries using the best possible analytical methods in order to optimize manufacturing processes and to better understand degradation processes in cell operation.

Responsible: MSc S. Schroeder, MSc K. Vettori


Polymer and Hybrid Solid Electrolytes:

Due to their good mechanical properties and ease of processing, polymers represent a promising class of substances for use in solid-state batteries. However, neither the interfacial reactions between polymer, active material and other solid electrolytes nor the lithium transport in these hybrid systems are fully understood. We therefore focus on the analytical and electrochemical characterization of these interfaces and aim to establish the study of these beam-sensitive polymer samples using cryo-SIMS and cryo-FIB.

MiNaBatt

Micro- to Nanoscale Investigation of Interfacial Processes in Solid-State Batteries with Hybrid Electrolytes to Elucidate the Lithium Transport

We start the international project MiNaBatt involving the Luxembourg Institute of Science and Technology (LIST) and the group of Dr. F. Richter from the University of Giessen (D). The aim is to investigate the mechanism of lithium-ion conduction through interfaces/interphases in hybrid electrolytes to improve interfacial engineering for future high energy chemical energy storage systems with longer lifetimes and safer performance.
