    Abstract: A battery includes a power generator and a covering body covering the power generator. The power generator includes a positive electrode layer, a negative electrode layer, and a solid electrolyte layer positioned between the positive electrode layer and the negative electrode layer. At least one selected from the group consisting of the positive electrode layer, the solid electrolyte layer, and the negative electrode layer contains a halogen-containing solid electrolyte. The covering body includes a base material layer, a resin layer, and a metal layer positioned between the base material layer and the resin layer. The resin layer is disposed so as to face the power generator and contains a halogen-containing polymer.

    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.
