Non-aqueous electrolyte secondary battery for X-ray diffraction measurement and X-ray diffraction measurement method

摘要

PROBLEM TO BE SOLVED: To provide: a battery which readily enables the high-sensitivity X-ray diffraction measurement by a transmission method, increased in X-ray transmittance, and arranged so that a lattice constant can be evaluated; and a method of X-ray diffraction measurement.SOLUTION: A nonaqueous electrolyte secondary battery for X-ray diffraction measurement comprises: a battery container which contains an electrode body including a positive electrode, a negative electrode and a separator disposed between the positive and negative electrodes, and a nonaqueous electrolyte to immerse the electrode body in. The negative electrode has an electrical current collector in its whole outer peripheral portion, and a part other than the outer peripheral portion. As to the negative electrode, a part of the negative electrode other than the electrical current collector is at least partially made of a material with a high X-ray transmittance. As to the battery container, at least a part of the battery container is made of a material high in X-ray transmittance. The electric current collector which is present in the part of the negative electrode other than the outer peripheral portion thereof, the material high in X-ray transmittance, and the high X-ray transmittance material of the battery container are disposed on an X-ray radiation route. A method of X-ray diffraction measurement is arranged with the nonaqueous electrolyte secondary battery for X-ray diffraction measurement.SELECTED DRAWING: None
