Assembly processes can be realized to be manual, hybrid or fully automated. In hybrid or fully automated assembly processes, the material flow is often disrupted through the utilization of sequential handling operations. As industry often aims to decrease manufacturing costs through an increased degree of automation, thus increasing the overall manufacturing productivity, handling processes need to be improved in terms of e.g. actuation times of grippers and reduced inertia of handling systems. This paper discusses the limitations in productivity of sequential handling tasks and the opportunities of significantly increasing manufacturing productivity through the utilization of continuous assembly procedure, instantiating it within the lithium-ion-battery production. 

Inline Monitoring of Battery Electrode Lamination Processes Based on Acoustic Measurements

et al. 2021

Due to the energy transition and the growth of electromobility, the demand for lithium-ion batteries has increased in recent years. Great demands are being placed on the quality of battery cells and their electrochemical properties. Therefore, the understanding of interactions between products and processes and the implementation of quality management measures are essential factors that requires inline capable process monitoring. In battery cell lamination processes, a typical problem source of quality issues can be seen in missing or misaligned components (anodes, cathodes and separators). An automatic detection of missing or misaligned components, however, has not been established thus far. In this study, acoustic measurements to detect components in battery cell lamination were applied. Although the use of acoustic measurement methods for process monitoring has already proven its usefulness in various fields of application, it has not yet been applied to battery cell production. While laminating battery electrodes and separators, acoustic emissions were recorded. Signal analysis and machine learning techniques were used to acoustically distinguish the individual components that have been processed. This way, the detection of components with a balanced accuracy of up to 83% was possible, proving the feasibility of the concept as an inline capable monitoring system.

“…The z ‐folding is thus an intermediate method between continuous winding and single‐sheet stacking of electrodes and separator. There are also modifications like continuous z ‐folding and integrated cut and place module . A stacking of single separator sheets is preferably avoided due to the static charge, which causes unwanted adhesion during handling .…”

“…In handling, serial operations are used, which lead to long cycle times because of to and fro movement between magazines loaded with material and the placement position in the ESA. A shortening of the time by increasing the acceleration of the automation device is limited due to inertia loads and the required deposition accuracy . For these reasons, a shortening of process time demands a precise investigation of the needed deposition accuracy.…”

Investigation of the Influence of Deposition Accuracy of Electrodes on the Electrochemical Properties of Lithium‐Ion Batteries

2019

View full text Add to dashboard Cite

Nowadays, battery production involves the use of cost‐intensive materials and highly complex production processes. The knowledge of interactions between product properties and process parameters is often limited to best‐practice‐experience rather than based on actual quantitative correlations. This work quantifies the influence of electrode deposition accuracy (process parameter) on the electrochemical performance (product property) of large battery cells (discharge capacity >8 Ah). In total, 40 lithium‐ion battery cells with five different deposition error configurations are manufactured and electrochemically tested. The electrochemical results of these tests show a linear decrease in the discharge capacity with a linear increase in the deposition error. The reduced discharge capacity is attributed to the extended nonoverlap of cathode and anode areas as well as the larger travel distances of intercalating ions.
