The subject of the present invention is a device for the in situ analysis of batteries by means of X-ray, synchrotron or another radiation. The device has a sample support, which is realized as a sample wheel rotatably mounted about the center axis. A plurality of sample holders, the center points of which are placed on a common circular line about the center point of the sample support, are arranged on the sample support, wherein each sample holder can be repeatedly opened and closed individually by an arrestable cover. Each sample holder has in its interior a cavity which receives the battery, which is to be examined, in a manner ideal in shape with regard to circumference, wherein the cover and the cavity have an opening for the passage of the beam. A spring, engaging in the edge region of the battery, presses the battery against the cover, wherein the spring and the edge region of the cover are embodied so as to be electrically conducting but insulated with respect to one another. There are directed from each sample holder an electrically conductive connection from the edge region of the cover, and an electrically conductive connection from the spring onto the face of the sample support facing away from the cover and into the vicinity of its center point. There, the lines of all sample holders are combined to form a line bundle or a plug connector.
