• All‐solid‐state batteries have piqued global research interest because of their unprecedented safety and high energy density. Significant advances have been made in achieving high room‐temperature ionic conductivity and good air stability of solid‐state electrolytes (SSEs), mitigating the challenges at the electrode–electrolyte interface, and developing feasible manufacturing processes. Along with the advances in fundamental study, all‐solid‐state pouch cells using inorganic SSEs have been widely demonstrated, revealing their immense potential for industrialization. This review provides an overview of inorganic all‐solid‐state pouch cells, focusing on ultrathin SSE membranes, sheet‐type thick solid‐state electrodes, and bipolar stacking. Moreover, several critical parameters directly influencing the energy density of all‐solid‐state Li‐ion and lithium–sulfur pouch cells are outlined. Finally, perspectives on all‐solid‐state pouch cells are provided and specific metrics to meet certain energy density targets are specified. This review looks to facilitate the development of inorganic all‐solid‐state pouch cells with high energy density and excellent safety. Research on all‐solid‐state batteries is currently transitioning from lab‐scale fundamental study to industry‐scale application research. This review provides a timely summary of the current progress on inorganic solid‐state electrolyte‐based all‐solid‐state pouch cells, analyzes their technical challenges, and outlines future research targets for realizing high‐energy‐density all‐solid‐state Li‐ion and lithium–sulfur batteries.
