The ZSW conducts research activities within the project Action that is part of the greenBatt research cluster. Thereby the ZSW places emphasis on production and comparative characterization of electrode slurries, electrodes and battery cells obtained from conventional active materials, and semi-finished products and battery cells, which contain a proportion of recycled active material. Particular interest is on rheological properties, stability (shelf life) and processability for electrode slurries. Electrodes are investigated regarding their morphological characteristics, adhesion coating/substrate, homogeneity and the tendency to form coating defects. The resulting battery cells are characterized in terms of cell performance, quality, safety and service life.
