Solid State Batteries – Next Generation of Energy Storage Technologies
Solid state battery research has made enormous progress in recent years, particularly in mobile applications. Novel solid-state batteries not only promise higher energy density and a longer service life, but also improved safety and environmental compatibility compared to conventional lithium-ion batteries. They can therefore play a key role in electromobility.
However, there are still some challenges, such as the search for high-performance and cost-efficient materials, the influence of interface effects within a device, and processability and economies of scale in battery production. Our research covers the entire process chain, from innovative material concepts and battery design to production processes on a specially designed pilot plant in Garching.
Materials
In the research field Material Design, we focus on material synthesis and scaling up synthesis processes. We conduct research on the development of novel ion-conducting materials, up to the targeted design of new material systems, such as the production of hybrid materials via electrospinning. We deliberately do not limit ourselves to a single class of materials but research across various material classes.
Single Cells and Analytics
In the research field Single Cells and Analytics our focus is on the development of analytical methods for battery cells, the production of sulfide electrolyte layers on a lab scale, and the scaling up of these processes. We develop and optimize specially adapted hardware to test the developed cells for its physical and electrochemical properties. Meanwhile a wide selection of analytical methods and the extensive expertise of our analytics team are available for our research on solid state batteries.
Production
In the research field Production we transfer the findings gained in lab scale experiments with sulfide electrolyte layers to the large-scale production processes. Our researchers test all relevant process steps, verifying and qualifying the materials for applicability in roll-to-roll printing. In collaboration with equipment manufacturers, prototype facilities for coating and calendaring the components have been developed and installed on campus.
Simulation Cluster
In the research field Simulation we develop novel simulation models to enable reliable predictions of cell behavior for novel material designs or cell concepts. This theoretical work is intended to enhance our understanding of processes within a solid state cell and to improve the performance of novel batteries.
