Problems solved by technology
Most of the existing foreign designs are expensive and complicated to operate, such as Japan Rigaku; in addition to most of the domestic commercialized reaction pools using beryllium windows that are likely to cause environmental pollution, most of them have single functions or poor contact between electrode materials and current collectors , it is difficult to realize the real in-situ XRD test under different atmospheres

Abstract
The invention relates to an in-situ battery reaction chamber of a multifunctional X-ray diffractometer, comprising: a base, the middle part of which is a circular base through groove, and the circular base through groove forms an upward circular shape compared with the peripheral part of the base. Ring-shaped protrusion; the negative base has a circular base channel with internal threads in the middle, and the base channel forms a downward ring-shaped protrusion compared with the peripheral part of the base; the base channel and the base channel are matched and connected, The bottom end of the base through groove is inserted into the base through groove; the negative electrode is a cylindrical structure with external threads, and its upper end extends into the base through groove, and is threadedly connected with the base through groove. It avoids the use of highly toxic beryllium windows, realizes the in-situ XRD detection of batteries under different gas atmospheres, and avoids the problem of poor contact between electrode materials and current collectors; the in-situ XRD battery reaction chamber can be used for two electrodes of various batteries system test.
Description
technical field [0001] The invention belongs to the technical field of in-situ XRD testing of batteries, and in particular relates to an in-situ battery reaction chamber of a multifunctional X-ray diffractometer and its application. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art.
