A fully solid-state battery mold realizes the tableting of solid electrolyte and the assembly of fully solid-state battery through a pressurizing device, and is connected to an electrochemical workstation through a tab. In addition, in-situ Raman and XRD characterizations are realized by replacing different test windows.

Description
Technical Field
The utility model relates to the technical field of all-solid-state batteries, is suitable for in-situ optical microscope, raman and XRD tests, and particularly relates to an all-solid-state battery mold.
Background
Currently, in all-solid-state battery systems, the side reactions of the electrolyte and the high-voltage positive electrode material under high pressure and the problem of lithium dendrite growth remain. How to detect the side reaction between the electrode and the electrolyte material and the structural evolution of the anode material under the in-situ working condition of the charging and discharging process has important significance for guiding the design of the electrode material and the electrolyte and improving the performance of the all-solid-state battery. In existing in situ characterization methods, the preparation of the electrolyte and the assembly of the battery are typically performed externally and then transferred to an in situ characterization mold for in situ testing. In this secondary transfer process, there is a release of battery pressure, and the test does not reflect the actual operating state of the battery.
In the existing all-solid-state battery mold, for example, in China patent 202223058289.1, an electrode material is pressurized in a screwing mode, and although electrolyte preparation and battery assembly can be performed, electrochemical performance test can be performed only, and in-situ multi-characterization test of spectroscopy such as Raman and XRD cannot be simultaneously satisfied. For all-solid-state battery systems, it is far from sufficient to detect electrode reactions and structural evolution by a single detection means only to truly reflect the operating state of the battery.
Therefore, if the die can be designed for both the synthesis and assembly of the all-solid-state battery and the satisfaction of various in-situ characterization technical requirements, the experimental process is greatly simplified, the interference caused by secondary transfer of the battery to different in-situ die characterization is avoided, and the accuracy and reliability of data are ensured.
