Abstract: There is provided a solid-state battery which can prevent short circuiting or breakage from occurring in electrode layers in individual laminates due to rolling when the stacked laminates are subjected to a high-pressure pressing process. A solid-state battery includes a laminate in which a positive electrode collector, a positive electrode active material layer, a solid electrolyte layer, a negative electrode active material layer, and a negative electrode collector are stacked in this order, and a conductive rigid body including a rigid body having electrical conductivity, wherein the laminate and the conductive rigid body are alternately stacked, and the conductive rigid body is provided on each outermost side in a stacking direction.

Abstract: A storage case of an electrode roll of a secondary battery having a hollow core and an electrode body wound around the core includes a case that covers the electrode roll. The storage case has a structure in which a space in which the electrode body is housed is sealed by the case and protrusions protruding in an axial direction of the core from end surfaces of the electrode body at both ends of the core.

Abstract: A lamination device is disposed downstream of a conveying device configured to convey a plurality of electrode bodies, and laminates the plurality of electrode bodies. The lamination device includes: a mounting plate on which the plurality of electrode bodies are laminated, the mounting plate being inclined with respect to the electrode bodies being conveyed by the conveying device; a first wall erected on the mounting plate and perpendicular to a conveying direction; and a drop prevention portion provided on the first wall or on a wall different from the first wall, the drop prevention portion preventing the plurality of electrode bodies from dropping from the mounting plate.
