Description
Summary:All-solid-state lithium-ion battery cells will consist of mechanically and chemically sensitive lithium metal anodes and solid-state electrolytes. In processing these components, mechanical damage to the active surface, contact with a humid atmosphere and potential particle contamination must be avoided as these have severe impact on cell performance. These requirements pose major challenges to handling in cell assembly, which is why a material-adapted handling system is developed. The handling system is capable of gripping and positioning the electrodes in conditioned atmosphere without mechanical damage. These system capabilities are evaluated in an automated stacking process for cell assembly of all-solid-state batteries.
