The pursuit of scalable and manufacturable all-solid-state batteries continues to intensify, motivated by the rapidly increasing demand for safe, dense electrical energy storage. In this perspective, we describe the numerous, often conflicting implications of materials choices that have been made in the search for effective mitigations to the interfacial instabilities plaguing solid-state batteries. Specifically, we show that the manufacturing scalability of solid-state batteries can be governed by at least three principal consequences of materials selection: (1) the availability, scaling capacity, and price volatility of the chosen materials’ constituents, (2) the manufacturing processes needed to integrate the chosen materials into full cells, and (3) the cell performance that may be practically achieved with the chosen materials and processes. While each of these factors is, in isolation, a pivotal determinant of manufacturing scalability, we show that consideration and optimization of their collective effects and trade-offs is necessary to more completely chart a scalable pathway to manufacturing.

由于对安全，密集的电能存储的迅速增长的需求，对可伸缩和可制造的全固态电池的追求不断增强。从这个角度出发，我们描述了在有效缓解固态电池困扰的界面不稳定性方面，材料选择所产生的众多且往往是相互矛盾的含义。具体而言，我们表明，固态电池的制造可扩展性可以由材料选择的至少三个主要结果决定：（1）所选材料成分的可用性，缩放能力和价格波动性；（2）制造将所选材料集成到完整电池中所需的过程，以及（3）使用所选材料和过程可以实际实现的电池性能。
