Abstract

This application provides an electrochemical in-situ XRD testing mold and system. The electrochemical in-situ XRD testing mold includes an upper template and a lower template. A through hole is formed in the middle of the upper template as a viewing window, and the lower template is detachably connected to the upper template. A sealing element is provided between the two templates, and after the battery under test is assembled between the upper and lower templates, the two ends of the sealing element abut against the corresponding upper and lower templates. It also includes a pressing component, located on the upper template and / or the lower template, for adjusting the pressing pressure of the battery under test in the installation space to ensure stable contact between the battery under test and the upper and lower templates. At the same time, the observation window of the in-situ battery reaction chamber is formed by drilling holes in the positive electrode shell, and the corresponding window material is selected according to the electrode material being tested. In this way, non-destructive observation and real-time online monitoring of liquid batteries can be achieved. The corresponding testing mold is convenient, efficient, reusable, versatile, and low-cost, which is beneficial for enterprises / related departments to reduce costs and increase efficiency.
