The rapid identification of critical compounds in recycling material streams is crucial for an adequate sorting. Recently, the development of adapted multi-sensor systems as well as advanced multi-source data fusion for real-time data integration is in the scope of several research activities. This work deals with the digitalisation of mechanical separation processes in recycling of Li-ion batteries using data which were acquired by hyperspectral sensors. In order to establish a reference data set of the valuable components Al and Cu, in this study a sample set of Al and Cu foils was examined by reflectance spectroscopy in the range (350 * 2500) nm. Based on point measurements and statistical data from imaging sensors, optical material characteristics of the samples were analysed. Proposals for optical sorting steps and possible challenges will be outlined and discussed. This work is financially supported by the Federal Ministry of Education and Research (BMBF) in the framework of the greenBatt cluster within the project DIGISORT.[1] [1] www.greenbatt-cluster.de/de/projekte/digisort/
