Abstract
A chemical state analysis apparatusincludes: an excitation sourceconfigured to irradiate an irradiation region A of a predetermined surface in a sample S containing a battery material with an excitation rays for generating characteristic X-rays of the battery material; an analyzing crystalof a flat plate arranged so as to face the irradiation region A; a slitarranged between the irradiation region A and the analyzing crystal, the slit being arranged in parallel to the irradiation region A and a predetermined crystal plane of the analyzing crystal; an X-ray linear sensorin which linear detecting elementseach having a length in a direction parallel to the slitare arranged in a direction perpendicular to the slit; a wavelength spectrum generation unitconfigured to generate a wavelength spectrum based on intensity of the characteristic X-rays detected by the X-ray linear sensor; a peak wavelength determination unitconfigured to determine a peak wavelength which is a wavelength in a peak of the wavelength spectrum; and a chemical state specification unitconfigured to specify a value for specifying a chemical state of the battery material in the sample S from the peak wavelength determined by the peak wavelength determination unitand a standard curve representing a relation between a value representing the chemical state and the peak wavelength.
