Prior information notice without call for competition: Miscellaneous special-purpose machinery Description of the procurement: In the field of electrode production, coating systems are put out to tender together with the drying line and solvent recovery. In order to be able to address the needs of FFB~s future customers with regard to their technological and throughput aspects, several variants of the systems are planned. For a high level of technological flexibility, 4 coating and drying systems, each with different characteristics, are provided: a production line in tandem mode, a production line in simultaneous mode, a test line and a sample line. The systems which are part of this prior publication are explained in more detail below. The sample line advertised in this prior publication is intended for the production of anodes and cathodes on a pilot plant scale. An aqueous suspension with active materials such as carbon or silicon is provided as the coating material for the anodes. Solvent-based suspensions with active materials such as NMC, NCA, LCO should be used for the cathode. For this purpose, the system should also be as compatible as possible with new and experimental active materials and solvents. Furthermore, a simple and quick change of operation with different suspension compositions should be possible. The system should enable coatings with a film width of approx. 400 mm and coating widths of at least 350 mm. The maximum speed of the system should be 10 m / min. The system should enable the greatest possible scaling flexibility at lower coating speeds. Both continuous and intermittent coating processes must be taken into account. The coating should be possible using both flat slot nozzles and comma knife methods. The switch between these two coating processes should be simple and possible in a short changeover time. The dryer length of the system results from the process time of the electrodes. For all lines, solutions should be available for the interfaces with mixing units (feed via ring line and batch container) and for process control technology and logistics control. In addition, all lines should have a solvent recovery system. From the point of view of a research factory, all systems should have short set-up and changeover times, as well as no complications with longer downtimes. A high scalability and flexibility of the processes should also be made possible. Furthermore, the systems should be cleaned quickly and easily.
