Participation in the Innovation Day for SMEs organised by the Federal Ministry of Economics and Climate Protection (BMWK)
On 13.06.2024, Tilmann Leisegang, together with Dr. Dominik Nuss from the Institute of Textile Machinery and High Performance Materials Technology at TU Dresden and Dr. Jens Harhausen from elfolion GmbH, presented the results of the ZIM-funded project "Development of film-like, resource-efficient, fabric-based current collectors for electrodes for high-energy and -power density lithium-ion cells made of ultra-fine glass multifilament yarns and metal wires (ZF4751502JO9)" as an exhibitor at the Innovation Day for SMEs organised by the Federal Ministry of Economics and Climate Protection (BMWK). He accepted the BMWK's invitation due to the "impressive results of the project" and thus represented the Institute of Experimental Physics at TU Bergakademie Freiberg, Energy Materials working group. elfolion GmbH presented the development of the innovation as part of the "stage talk".
The Innovation Day for SMEs, organised by the BMWK in Berlin Pankow, stands for innovative projects, high-performance companies and bright minds. Under the motto This is how the future works! - Digital. Transformative. Resilient., visitors could feel the creative energy with which SMEs are tackling the issues of the future and driving technological change. At the open-air event, SMEs and the research institutions cooperating with them had the opportunity to present their pioneering developments, which have been realised with the support of the BMWK's open-topic innovation funding. The Federal Minister of Economics and Climate Protection, Dr Robert Habeck, was also present.

High-throughput screening of inorganic crystal structures finds new class of ionic conductors with La3CuSiS7 structure
Together with the SCTMS, a high-throughput screening of the Inorganic Crystal Strcuture Database (ICSD) for new promising Ca2+-, Mg2+-, Zn2+- und Al3+-ion-conducting ternary and quaternary sulfides, selenides and tellurides (∼1500 compounds) was performed. A geometric topological approach based on Voronoi partitioning was initially applied and yielded 104 compounds that were unknown as ion conductors with possible cation conduction. All compounds were subjected to bond valence site energy analysis to determine the migration energy. In addition, the logarithmic dependencies of migration energy on the geometric parameters of the migration pathways were determined. As a result, 16 out of 104 structures were filtered out as promising ionic conductors. Finally, density functional theory calculations revealed 11 most promising compounds with migration energies < 1.0 eV. Among them is a new class of ionic conductors with the structure La3CuSiS7, for which ab initio molecular dynamics calculations were performed. These resulted in diffusion coefficients of ∼10-7 cm2 s-1 and ionic conductivities of ∼10-2 S cm-1 at 300 K. The results were added to the Battery Materials Database.
