Challenges and requirements for the large-scale production of all-solid-state lithium-ion and lithium metal batteries are herein evaluated via workshops with experts from renowned research institutes, material suppliers, and automotive manufacturers. Aiming to bridge the gap between materials research and industrial mass production, possible solutions for the production chains of sulfide and oxide based all-solid-state batteries from electrode fabrication to cell assembly and quality control are presented. Based on these findings, a detailed comparison of the production processes for a sulfide based all-solid-state battery with conventional lithium-ion cell production is given, showing that processes for composite electrode fabrication can be adapted with some effort, while the fabrication of the solid electrolyte separator layer and the integration of a lithium metal anode will require completely new processes. This work identifies the major steps towards mass production of all-solid-state batteries, giving insight into promising manufacturing technologies and helping stakeholders, such as machine engineering, cell producers, and original equipment manufacturers, to plan the next steps towards safer batteries with increased storage capacity.

本文通过与来自知名研究机构，材料供应商和汽车制造商的专家的研讨会，对大规模生产全固态锂离子和锂金属电池的挑战和要求进行了评估。为了弥合材料研究和工业批量生产之间的差距，提出了基于硫化物和氧化物的全固态电池生产链从电极制造到电池组装和质量控制的可能解决方案。根据这些发现，详细比较了基于硫化物的全固态电池与常规锂离子电池的生产工艺，表明可以很费力地调整复合电极的生产工艺，而固体电解质隔板层的制造和锂金属阳极的集成将需要全新的工艺。这项工作确定了全固态电池大规模生产的主要步骤，深入了解了有前途的制造技术，并帮助利益相关者（例如机械工程，电池生产商和原始设备制造商）计划了逐步实现更安全的电池的下一步计划存储容量。
