The development of new batteries with high energy densities, faster kinetics and higher stability requires targeted basic research. To do this, it is necessary to determine which reversible electrochemical processes take place at high cell voltages and currents. In the electrochemistry research field, the scientists examine the interfaces between the electrode (electron conductor) and electrolyte (ion conductor), where the battery-specific redox reaction takes place.
Read moreThe aim of the materials research field is to identify novel materials with potentially higher energy densities that are safe and can be produced at lower costs. In addition, these should enable rapid charging and discharging over many cycles. A new development or optimization of both the electrode and the electrolyte materials is necessary.
Read moreIn this research field, the scientists at the HIU deal with the theoretical description of processes that take place in batteries (e.g. during charging or discharging). The composition and behavior of structures are modeled in order to be able to estimate material properties that are relevant for electrochemical energy storage. For example, the formation of structures through chemical processes is simulated at the atomic level.
Read moreThe scientists in the Systems research field test and characterize the electrical properties of commercial battery cells, e.g. to evaluate aging processes in a battery in a holistic and system-oriented manner. In this way they lay the foundations for further optimization of the batteries. The focus is, among other things, on the life cycle of commercially available cells (e.g. with newly developed cell chemistry) and their evaluation with regard to potential fields of application.
Read moreResearch in the research field methods focuses on the development and targeted application of selected analysis techniques to make reaction pathways and atomic phenomena of electrode materials and cells visible. In order to guarantee a long service life and safe operation of batteries, detailed knowledge of the processes involved in charging and discharging is required. These can only be recorded using special examination methods, which are further developed accordingly.
