1. A structure for battery analysis comprising:
a battery accommodation unit in which a hollow portion for accommodating a sample battery therein is formed;
a pressurizing unit that is mounted on one end surface side of the battery accommodation unit and includes a pressurizing mechanism for applying pressure to the sample battery accommodated in the hollow portion of the battery accommodation unit; and
a pressure receiving unit that is fixed to the other end surface side of the battery accommodation unit and receives pressure acting on the sample battery, wherein the pressure receiving unit includes an X-ray window for irradiating the sample battery accommodated in the hollow portion of the battery accommodation unit with X-rays and emitting diffracted X-rays reflected from the sample battery to an outside, the X-ray window being formed by a cutout hole penetrating from a front surface to a back surface, and a partition member for transmitting X-rays therethrough and shielding the hollow portion in the battery accommodation unit from an atmosphere is arranged in the X-ray window;
wherein the sample battery is configured so that electrode active material layers are arranged on both end sides of an electrolyte layer and current collector layers are further arranged outside the electrode active material layers respectively, and a first electrode terminal that is electrically conducted to one of the current collector layers, and a second electrode terminal that is electrically conducted to the other current collector layer are provided outside.
