Climate change is causing dramatic shifts in nature, leading to disruptions in ecosystems and significantly influencing the everyday life of humans. As it is highly affecting the balance of the natural world, the most significant contributors to greenhouse gas emissions are undergoing a major change towards sustainability. As one of the biggest contributors, the transportation sector is experiencing a disruption. Efforts to mitigate climate change are driving the development of cleaner transportation technologies and policies to reduce emissions from the sector.
One goal is the shift towards electric mobility, highlighting the core component, the battery storage system. The urgent need for high-performance battery storage leads to increased research on innovative battery materials and cell designs. One of the most promising cell concepts, the all-solid-state battery (ASSB), is emerging as a game-changing technology with high potential to improve safety, energy density, and costs. Using sulfide-based materials showed promising results in laboratory cells with high potential to be applied in electric vehicles. However, the current state-of-the-art exhibits a vast gap between results from the laboratory and the mass production of efficient large-format battery cells.
This thesis aims to bridge the gap between laboratory and pilot production of sulfide-based ASSBs. The topic is motivated by presenting the state-of-the-art laboratory experiments coating small-format ASSB cells and large-scale fabrication of lithium-ion batteries (LIBs). The need for action is derived and the framework of the dissertation are set. The focus is on the wet coating process, including analyzing intermediate products from the slurry, wet and dry coating. The results are presented in a cumulative overview of seven publications, giving theoretical and experimental insights into the correlation of product and process parameters for sulfide-based materials in ASSBs. Besides the processes, also pilot machinery is addressed, concluding in the setup of an entirely housed roll-to-roll coater at the Institute for Machine Tools and Industrial Management (iwb).
