摘要： A sealed secondary battery deterioration diagnosis method comprising a step of detecting deformation of the sealed secondary battery (2) and obtaining a first curved line (L1) representing a relationship between a discharged capacity from a fully charged state or a charged capacity up to the fully charged state and a detected deformation amount of the sealed secondary battery (2), a step of obtaining a second curved line (L2) representing a relationship between the charged/discharged capacity and a slope of the first curved line (L1), and a step of determining that the battery is in a deterioration mode brought about by enlargement of reaction distribution when the charged/discharged capacity calculated on the basis of a width of a peak appearing on the second curved line (L2) is larger than the charged/discharged capacity calculated on the basis of a width of a corresponding peak in the predetermined reference state.
