Summary of the overall project:

The aim of the joint project is to create the plant technology and intelligent control strategies for the production system for "granulate-based one-step electrode production" initialized as part of the BMBF project "HEMkoop". This novel production system integrates the sub-steps coating, drying and compaction in one plant technology ("single-step plant") and thus significantly reduces investment and operating costs compared to the conventional production of electrodes so far. High drying costs are minimized by a significant reduction of the solvent content of at least 10 and 25 wt.% for cathodes and anodes, respectively, which additionally leads to a significantly lower GWP/CO2 footprint and thus to a higher ecological efficiency of the production technology. Furthermore, in contrast to suspension-based traditional coating processes, granules from an energy-efficient extruder process serve as input materials. During drying, no layer shrinkage and thus no component segregation (binder/carbon black) occurs, as is the case with SdT productions.

Goals and tasks of iPAT (AG Schilde)

• Development of a grey box model for the novel coating process
• Adaptation of the digital twin to the machine environment
• Creation of a uniform software environment that can be used for plant control
• Development and programming of a validated and optimized digital twin for the plant control system
• First adaptations of the digital twin to a varying granulate recipeErste
