Abstract

The invention belongs to the field of battery in-situ tests and electrochemistry, and relates to a battery for an in-situ XRD (x-ray powder diffraction) test and an assembly method of the battery. According to the battery for the in-situ XRD (x-ray powder diffraction) test and the assembly method of the battery, on the basis of the characteristics and requirements of existing battery in-situ XRD tests, the in-situ XRD test process of a battery electrode material is redesigned; carbon paper, replacing traditional metal beryllium, is adopted as a window material for the in-situ XRD test of the battery electrode material. The assembly method is applied to the in-situ XRD test of the battery electrode material so as to test products and phase change of the battery electrode material during a charging and discharging in a more inexpensive and environmentally friendly manner, so that the reaction mechanism of a battery charging and charging process can be researched. Therefore, the technicalproblems of high cost, environmental pollution and complicated assembly steps of an existing method adopts a beryllium window mold to perform an in-situ XRD test are solved.

Description

technical field [0001] The invention belongs to the fields of battery in-situ testing and electrochemistry, and more specifically relates to a battery used for in-situ XRD testing and an assembly method thereof. Background technique [0002] X-ray powder diffraction (XRD) is a rapid analytical technique primarily used for phase identification of crystalline materials and can provide information about unit cell dimensions. The analyzed material was finely ground, homogenized, and the average bulk composition determined. X-ray powder diffraction (XRD) is most widely used to identify unknown crystalline materials (eg minerals, inorganic compounds). Furthermore, X-ray powder diffraction (XRD) can also be used to characterize crystalline materials, identify fine-grained minerals that are difficult to measure optically (such as clays and mixed-layer clays), and measure unit cell size and sample purity. [0003] During the charge and discharge process of the battery, the crystall...
