Handling Cell Components in the Production of Multi-Layered Large Format All-Solid-State Batteries with Lithium Anode

摘要

All-solid-state batteries (ASSB) are considered as promising energy storage systems for consumer electronics and electric mobility because of their high safety, long life and high energy density. Currently, electrochemistry and materials research attempt to produce ASSB cells on laboratory scale. One future challenge will be to characterize the required manufacturing processes for large format composites of thin ceramic layers used in ASSB and to transfer this knowledge to pilot scale production. The promising technology is still far from being commercially producible on an industrial scale, which is why there is a particular need for extensive research on the manufacturability of large format and stackable sheet type ASSB cells. In this paper we present a concept for handling cell components during cell assembly of ASSB by analyzing extensively the material and process requirements, as well as interdependencies with simultaneous engineering. Furthermore, the possibilities for cell stacking are investigated via SIPOC by appropriately adapting techniques of conventional lithium-ion batteries to the varying requirements of ASSB.
