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.

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. [0003] As an effective electrochemical energy storage device, rechargeable batteries have attracted more and more attention from researchers. As an important part of rechargeable batteries, electrode materials play a vital role in the charging and discharging process of batteries. During the charging and discharging process of the battery, the microstructure of the electrode material will continue to ch...
