Multifunctional X-ray diffractometer in-situ battery reaction chamber and application

Abstract

The present invention relates to a multifunctional X-ray diffractometer in-situ battery reaction chamber, which comprises: a base, the middle part of which is a circular base through groove, and the circular base through groove forms an upward annular protrusion relative to the peripheral part of the base; a negative electrode pedestal, wherein the middle part of the negative electrode pedestal isprovided with a circular pedestal through groove with an internal thread, and the pedestal through groove forms a downward annular protrusion relative to the peripheral part of the base; the base through groove is connected with the pedestal through groove in a matched mode, and the bottom end of the pedestal through groove is sleeved with the base through groove. The chamber also includes a negative electrode that is of a cylinder structure with external threads, and the upper end of the negative electrode extends into the pedestal through groove and is in threaded connection with the pedestal through groove. A highly toxic beryllium window is prevented from being used, in-situ XRD detection of the battery under different gas atmospheres is realized, and the problem of poor contact between an electrode material and a current collector is avoided; the in-situ XRD battery reaction chamber can be used for testing a two-electrode system of various batteries.

AI Technical Summary

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
