Abstract: A battery includes a power-generating element and an insulating layer. The power-generating element includes an electrode layer, a counter-electrode layer placed to face the electrode layer, and a solid electrolyte layer located between the electrode layer and the counter-electrode layer. The insulating layer includes a first insulating film that extends inward from ends of the power-generating element in a planar view of a principal surface of the power-generating element and a second insulating film that covers a side surface of the power-generating element and that is continuous with ends of the first insulating film. The second insulating film is thinner than the first insulating film.

Abstract: An electrode includes an active material layer that includes an active material, a solid electrolyte, and a binder and a current collector that includes a substrate and a coating layer coating the substrate and being in contact with the active material layer. The binder includes a block copolymer that includes two first blocks constituted of a repeating unit having an aromatic ring and a second block located between the two first blocks. The weight average molecular weight of the block copolymer is 170,000 or more. The coating layer includes conductive carbon.

Abstract: The disclosed battery includes a laminated body and a housing. The laminated body includes first and second main surfaces, and a side surface parallel to a first direction which is the laminating direction. The housing includes a first housing portion including a first plate-shaped portion facing the first main surface, and a first side wall portion facing the side surface, and a second housing portion including a second plate-shaped portion facing the second main surface, and a second side wall portion facing the side surface. The first and second side wall portions include first and second projecting regions, respectively. The first and second side wall portions do not overlap each other when viewed from a second direction perpendicular to the side surface. The first and second projecting regions at least partially overlap each other when viewed from a third direction perpendicular to the first direction and along the side surface.

Abstract: An ion conductor material includes a solid-electrolyte material and a resin binder. The solid-electrolyte material includes Li, M, and X. The M is at least one selected from the group consisting of metal and metalloid elements other than Li. The X is at least one selected from the group consisting of F, Cl, Br, and I. The molar ratio of a modification group included in the resin binder to the solid-electrolyte material is less than or equal to 0.0002.

Abstract: Provided is a solid electrolyte material composed of Li, M, and X, where M is at least one kind of element selected from the group consisting of metalloid elements and metallic elements other than Li, and X is at least one kind of element selected from the group consisting of F, Cl, Br and I. In the solid electrolyte material, the mathematical formula FWHM/2θp≤0.015 is satisfied, where FWHM represents a half bandwidth of an X-ray diffraction peak having the highest intensity within a range of a diffraction angle 2θ of not less than 25 degrees and not more than 35 degrees in an X-ray diffraction pattern provided by an X-ray diffraction measurement of the solid electrolyte material; the X-ray diffraction measurement using a Cu-Kα ray; and 2θp represents a diffraction angle of a center of the X-ray diffraction peak. A value rCA provided by dividing a sum of ionic radii of Li and M by a sum of ionic radii of X is more than 0.261 and less than 0.306. A value of a difference ΔX between average electronegativity of M and average electronegativity of X is not less than 1.7.
