    Abstract: To provide a solid-state battery module and a separator which can apply sufficient surface pressure to a solid-state battery cell and are excellent in durability and vibration resistance. A separator (120) disposed between adjacent solid-state battery cells (101) in a solid-state battery module (100) including a plurality of solid-state battery cells (101) to electrically insulate the adjacent solid-state battery cells (101) of the plurality of solid-state battery cells (101), from each other. The separator (120) includes elastically deformable elastic members (123a, 123b) which apply biasing force in the stacking directions of the plurality of solid-state battery cells (101). Durability and vibration resistance can be obtained by adequately fixing the solid-state battery cells (101) with the elastic members (123a, 123b).

    Abstract: An all-solid-state battery includes a laminated body in which a positive electrode layer, a sulfide-based solid electrolyte layer; and a negative electrode layer are laminated; an absorber configured to absorb hydrogen sulfide gas; and an outer package configured to form a housing space in which the laminated body and the absorber are housed. The outer package includes a sealing portion configured to hermetically seal the housing space. The sealing portion includes a fragile portion whose sealing strength is weaker than that of the other portion of the sealing portion. In a case where the hydrogen sulfide gas is generated in the housing space, sealing of the fragile portion is released earlier than the other portion to form a discharge port through which the hydrogen sulfide gas is discharged to an outside of the housing space.
