Production Technologies for Sulfide- and Oxide-Based All-Solid-State Batteries

摘要

All-solid-state batteries (ASSBs) offer the potential for safe energy storage with a significant increase of energy density compared to conventional lithium-ion batteries. Here, we present our latest research on possible production technologies for ASSBs composed of sulfide and oxide ceramics. A systematic identification and evaluation of manufacturing technologies for other ceramic energy systems, such as solid-oxide fuel cells and ceramic capacitors, has been carried out. Based on a requirements analysis, production processes for fabrication of ceramic layers were assessed towards their applicability in the production of ASSBs. The most promising technologies were compared using Monte-Carlo simulations for the assessment of technology readiness. The subsequent generation of technology chains results in a conclusion about the adaptability of the introduced technologies to ASSBs as well as the comparison of these technologies to the current production of conventional lithium-ion batteries. The comprehensive overview and systematic analysis of production scenarios reveals development needs for machine engineering, component suppliers, and cell manufacturers. Based on these findings, scenarios for the scale-up from laboratory research to pilot scale can be derived.
