Analysis of energy and battery materials. Our range of services focuses on the characterization of battery materials and the optimization of electrodes for various energy storage systems. We analyze the material composition of electrodes to improve the performance and efficiency of lithium-ion batteries.

Special attention is paid to the study of the electrode-electrolyte interaction, in particular the Solid Electrolyte Interface (SEI). Through detailed investigations at this interface, we gain a better understanding of the processes during charging and discharging. The analytical results help to find solutions to increase the stability and lifetime of batteries.

Another focus of our work is the analysis of coatings that reduce aging processes in batteries. In particular, we investigate lithium plating and other lithium compounds that can affect the performance of battery systems.

By using state-of-the-art techniques such as Scanning Electron Microscopy (SEM), Focused Ion Beam (FIB), Transmission Electron Microscopy (TEM), Electron Energy Loss Spectroscopy (EELS), Energy Dispersive X-ray Spectroscopy (EDX) and Secondary Ion Mass Spectrometry with Time-of-Flight Analyzer (SIMS-TOF) we gain deep insights into the structure and properties of the materials.

To ensure the accuracy and reproducibility of our analyses and results, we perform all investigations in a controlled argon atmosphere using Glovbox and transfer shuttle. This allows us to analyze the materials under optimal conditions.

Our highly qualified interdisciplinary team of scientists meets individual requirements for customized analyses.
