All-solid-state lithium batteries (ASSLBs) employing sulfide solid electrolytes (SEs) promise sustainable energy storage systems with energy-dense integration and critical intrinsic safety, yet they still require cost-effective manufacturing and the integration of thin membrane-based SE separators into large-format cells to achieve scalable deployment. This review, based on an overview of sulfide SE materials, is expounded on why implementing a thin membrane-based separator is the priority for mass production of ASSLBs and critical criteria for capturing a high-quality thin sulfide SE membrane are identified. Moreover, from the aspects of material availability, membrane processing, and cell integration, the major challenges and associated strategies are described to meet these criteria throughout the whole manufacturing chain to provide a realistic assessment of the current status of sulfide SE membranes. Finally, future directions and prospects for scalable and manufacturable sulfide SE membranes for ASSLBs are presented.
采用硫化物固体电解质（SEs）的全固态锂电池（ASSLBs）有望实现具有能量密集集成和关键本质安全性的可持续储能系统，但它们仍需要具有成本效益的制造方法，并且需要将基于薄膜的SE隔膜集成到大型电池中以实现可扩展部署。本综述基于对硫化物SE材料的概述，阐述了为何实施基于薄膜的隔膜是ASSLBs大规模生产的优先事项，并确定了获得高质量硫化物SE薄膜的关键标准。此外，从材料可用性、薄膜加工和电池集成等方面，描述了在整个制造链中满足这些标准的主要挑战及相关策略，以对硫化物SE薄膜的当前状态进行实际评估。最后，介绍了用于ASSLBs的可扩展且可制造的硫化物SE薄膜的未来方向和前景。
