Functional Materials and Material Analysis for High Power Lithium-Ion Batteries

Contact Person: Dr.-Ing. Wolfgang Haselrieder

In the framework of the joined DFG research project “Development and Characterisation of Electrodes and its Production Process for Innovative Secondary Lithium-Ion-Batteries” optimisation of such systems is done in terms of process engineering together with the “Zentrum für Sonnenenergie- und Wasserstoff-Forsschung (ZSW)”. Research is performed on the production process of composite electrodes utilised for secondary Lithium-Ion-Batteries with respect to high-power applications, such as Hybrid-Electronic-Vehicles (HEV) and intermediate power storage of solar and wind energy.

The production process includes a pre-treatment of the primary products (composite fabrication, dosage, mixing), the formulation and the dispersing of particle suspensions (slurries), the coating- & drying-process, and finally the compaction through a calander.

Particles, suspensions and fabricated electrodes are for instance characterised by SEM images, mercury intrusion, BET, particle size and conductivity measurements. Furthermore diagnostic has a focus on the mechanical properties of the film and its adherence on the substrate. Therefore a Nanoindenter is utilised for indentations and nano-scratch-tests. Adherence is quantified by self developed failure tests. The electrochemical performance will be measured by the project partner Zentrum für Sonnenenergie- und Wasserstoff-Forschung.
