Abstract

The production of lithium-ion battery cells is composed of heterogeneous processes, each defined by parameters that influence the properties of intermediate and final products. Due to these complex interdependencies, process variations also affect production performance. Against this background, this works proposes a process design concept that combines process and production-oriented models. The case study investigates different coating speeds and drying temperatures considering process quality criteria, throughput, machine utilisation, and total energy demand. The results show that process-specific changes affect unequally the entire process chain and highlight the importance of a comprehensive approach targeting quality and energy efficiency.
