Im Kontext der Elektromobilität besitzt die Pouchzelle durch ihre hohe volumetrische und gravimetrische Energiedichte hervorragende Applikationseigenschaften. Die Herstellung des Elektroden-Separator-Zellverbunds ist durch die sequenzielle Abfolge von Zu- und Rückstellbewegungen – zurzeit ausgeführt von Industrierobotern – ineffizient und kostentreibend. Vorgestellt wird das Konzept einer vollautomatisierten Anlage mit einer kontinuierlichen Verfahrensführung ohne Verwendung von Zu- und Rückstellbewegungen.   In the context of electromobility, the pouch cell has distinctive advantages due to its high volumetric and gravimetric energy density. Manufacturing the electrode-separator-compound is inefficient and partly responsible for high manufacturing costs due to the required sequential setting and resetting movements of industrial robots carrying them out. A concept of a fully automated machine is presented, which uses a continuous process flow and avoids setting and resetting movements.

Das Handhaben von Elektrodenfolien ist ein entscheidender Prozessschritt bei der Montage von Batteriezellen. Aktuelle Verfahren zum Handhaben sind durch getaktete Pick-und-Place-Operationen gekennzeichnet. Ihre Produktivität ist dabei vom Bewegungsablauf mit den erforderlichen Rück- und Zustellbewegungen begrenzt. Vorgestellt wird das Konzept einer Bewegungseinrichtung für eine durchsatzgesteigerte Handhabung ohne Rück- und Zustellbewegungen sowie durch eine kontinuierliche Bewegung.   The handling of electrodes is an essential process step in the assembling of lithium-ion battery cells. Current methods for handling are characterized through pick-and-place operations. Their productivity is limited through the necessary setting and resetting movements. A concept of an apparatus for the handling of electrodes is introduced. Without setting and resetting movements as well as a continuous process flow, the productivity for handling electrodes can be significantly increased.

Lithium-ion batteries are being implemented in different large-scale applications, including aerospace and electric vehicles. For these utilizations, it is essential to improve battery cells with a great life cycle because a battery substitute is costly. For their implementation in real applications, lithium-ion battery cells undergo extension during the course of discharging and charging. To avoid disconnection among battery pack ingredients and deformity during cycling, compacting force is exerted to battery packs in electric vehicles. This research used a mechanical design feature that can address these issues. This investigation exhibits a comprehensive description of the experimental setup that can be used for battery testing under pressure to consider lithium-ion batteries’ safety, which could be employed in electrified transportation. Besides, this investigation strives to demonstrate how exterior force affects a lithium-ion battery cell’s performance and behavior corresponding to static exterior force by monitoring the applied pressure at the dissimilar state of charge. Electrochemical impedance spectroscopy was used as the primary technique for this research. It was concluded that the profiles of the achieved spectrums from the experiments seem entirely dissimilar in comparison with the cases without external pressure. By employing electrochemical impedance spectroscopy, it was noticed that the pure ohmic resistance, which is related to ion transport resistance of the separator, could substantially result in the corresponding resistance increase.
