Description

Solid electrolyte pressurizing device Technical Field The utility model relates to the field of solid-state batteries, in particular to solid-state electrolyte pressurizing equipment. Background The solid electrolyte of the solid-state battery is the most important core component, and the most important performance indexes for judging the performance of the solid-state electrolyte are ion conductivity, lithium metal interface stability and full battery performance. Currently, when testing (i.e., a testing process) of different items on a solid electrolyte, the solid electrolyte needs to be pressurized. The conventional pressurizing method for the solid electrolyte comprises the steps of firstly placing the solid electrolyte into a testing fixture (the testing fixture is provided with at least two pressurizing plates and a plurality of bolt assemblies for connecting the two pressurizing plates), then pressurizing the testing fixture to a required pressure through a pressurizing device (such as a jack), then manually locking each bolt assembly of the testing fixture by an operator, so that the testing fixture can stably pressurize the solid electrolyte, and finally releasing the pressurizing device from pressurizing the testing fixture and taking out the testing fixture. Because the operator manually locks each bolt assembly of the test fixture, the locking degree of each bolt assembly is different, so that the two pressurizing plates of the test fixture are not parallel, the solid electrolyte is not uniformly pressed, and the test result is affected. In view of the above-described problems, it is necessary to study a solid electrolyte pressurizing apparatus that can uniformly pressurize a solid electrolyte.
