Joint project
EXC 2154 POLiS - Post Lithium Storage Cluster of Excellence
Funder: German Research Foundation; Federal Ministry of Research, Technology and Space, former: Federal Ministry of Education and Research

Abstract:
The Cluster aims at developing electrode materials and electrolytes that allow for sustainable systems based on Sodium, Magnesium, Calcium, Aluminium, and Clorine ions.
Detailed description:
The major challenges of our research project are addressed in five research groups, which are dedicated to the four main topics Electrode Materials, Electrolytes, Interfaces, Integration & Sustainable Cell Technology and Cross-sectional Topics. POLiS follows a multidisciplinary approach, including solution and materials chemistry, electro-chemistry, predictive atomistic and continuum modelling, as well as chemical and process engineering. Arising concepts for materials design will be validated in full battery cells, examining performance, sustainability and safety issues.
Research Unit A - Electrode Materials
Electrode materials define and limit the amount of energy that can be stored per weight and volume of a battery. Our goal is to identify, synthesize and test new high-capacity post-lithium storage materials and thereby gain an even deeper understanding of their functionality.
Research Unit B - Electrolytes
Electrolytes enable the transport of electrically charged particles (ions) between the two electrodes of a battery. The main objective is the identification, synthesis and testing of new, stable and highly efficient liquid or solid transfer systems for post-lithium-ions.
Research Unit C - Interfaces
We aim to understand the formation and nature of interfaces that form within a post-Li battery - e.g. at the contact between electrode and liquid or solid electrolyte. Their microstructure and chemical composition have a decisive influence on the interface processes within the battery and thus determine, among other things, its performance and longevity.
Research Unit D - Integration and Sustainable Cell Engineering
Up-scaling of materials synthesis and cell construction, studies on the production capability of new technical approaches, assessment of cell safety and life cycle analyses of new technologies will pave the way for technology transfer. Central research data management and the development of automated data analysis tools will flank all work in the Cluster, set standards for the handling of research data and enable integrative, cross-research field data analysis, which we hope will lead to new insights in battery research.
Research Unit X - Cross-sectional Topics
In this research unit, innovative topics such as potassium batteries, organic redox systems, AI-supported virtual simulations or degradation are investigated. For this purpose, the competences from all other units are combined.
