STRUCTURE FOR PRESSURIZATION ANALYSIS, X-RAY DIFFRACTION APPARATUS AND PRESSURIZATION ANALYSIS SYSTEM

A structure for pressurization analysis includes a sample accommodating unit () for accommodating an all-solid-state battery (S) therein, and a pressurizing unit () having a pressurizing mechanism for causing pressure to act on the all-solid-state battery (S). The all-solid-state battery (S) is pressurized inside the sample accommodating unit () while being sandwiched between a pressure receiving member () and a pressing member (). Further, an X-ray window () is provided in an outer radial direction orthogonal to an acting direction of the pressure from the pressurizing unit (), and reflection type X-ray diffraction measurement can be performed through the X-ray window ().
