Electromobility and stationary energy storage require novel material combinations with advantages over conventional systems, for example in terms of higher energy density or lower costs. Fraunhofer ICT conducts research on numerous promising systems, e.g. lithium-sulfur cells, sodium-sulfur cells and silicon anodes, aiming to develop them to application level.
Development of electrolytes and membranes
The electrolyte is the core component in achieving material combinations with higher energy densities and a longer service life. Fraunhofer ICT investigates and continuously optimizes electrolytes with regard to their stability and performance. Dense, ion-conducting membranes can prevent electrolyte degradation and are therefore an important focus of research.
Construction of demonstrators
After a certain development stage, only limited information can be obtained from button cells. Fraunhofer ICT produces small multi-layered pouch cells for materials research.
