Evaluating Impedance Results of Lithium-Ion Batteries by DRT
The EMPIR-Project LiB4SecUse (Lithium Batteries for Second Use) develops impedance spectroscopy based techniques for the prediction of the state-of-health (SOH) of Lithium-Ion Batteries to asses their usability in second life applications. The Distribution of relaxation times (DRT) technique allows detailled interpretation of the spectra of Lithium-Ion batteries and is there-fore a promissing approach for fast […]
Characterization of calandered cathodes of li-ion battery cells using confocal and electron microscopy
The capacities and volumetric energy densities of li-ion battery cells can be raised by applying higher compressions on the electrodes. The calendering process does not only have a notable effect on the coating, it also has an effect on the current collector foil. In this study the focus is on the cathode and in particular […]

Methods for scalable production of solid-state batteries based on sulfide solid electrolytes
The increasing demand of electrically powered vehicles requires new battery technologies with higher safety and better performance than common lithium ion batteries (LIB) can provide. Solid-state batteries (SSBs) with a solid electrolyte (SE) of high ionic conductivity instead of organic liquid electrolytes are the most promising candidates to reach both requirements at the same time. […]
