For this reason, a design of an automated assembly station for all-solid-state battery cell manufacturing is proposed, that considers the material and process specific requirements.
In lithium-ion battery production, the assembly of the battery cells is subsequent to the electrode manufacturing process and is carried out in several interlinked process steps. Electrodes are handled in many of the process steps (e.g. drying, cutting, stacking), but the most crucial one is the stacking step.
Therefore, material-adapted processes are essential to ensure quality-assured manufacturing of all-solid-state lithium-ion battery cells. This paper presents the development of a scaled and flexible automated assembly station adapted to the challenging properties of the new all-solid-state battery materials.
The modified materials and cell design compared to the currently predominating lithium-ion batteries (LIBs) entail significant changes in manufacturing, rendering existing industrial battery production lines incompatible with lithium-metal-based ASSB fabrication.
Lithium-ion battery cells are one of the key technologies to promote the global and sustainable energy revolution. However, their electrochemical performance, safety and cost-effectiveness over the entire life cycle need to be further improved [ 1 ].
Summarizing all the modules, the automated assembly station is similar to the production technology of industrial stacking processes and at the same time flexibly adaptable and expandable.
