For the investigation of film drying processes, the measurement with Inverse Micro Raman Spectroscopy was established at the institute. In addition, various specially designed systems are available for drying investigations, which allow different drying conditions relevant to industry to be set and the processes to be investigated in detail. Within the framework of BMBF-funded projects in the ProZell consortium, investigations were carried out on the influence of drying processes on the structure and properties of high-capacity electrodes in their manufacturing. Part of a continuing project is to investigate the mass transport of the solvent NMP in battery electrodes and their materials. In addition, modeling of roll-to-roll infrared and vacuum drying processes based on investigations of the phase equilibrium of water in electrodes, their individual components and in separators was carried out in a BMBF project and a BMWi-AiF project.
