Abstract

The invention discloses a fixture for a conductivity test and an assembling method thereof. The fixture comprises a precise pretightening sliding mechanism, a fixing border, and a clamping module assembly for fixing electrolyte, wherein the precise pretightening sliding mechanism comprises a pressing head and a positioning head matched with the pressing head; a screw is fixed on the pressing head; sliding chute fixing side plates are arranged on two sides of the fixing border; the clamping module assembly has two types which can be used for a solid electrolyte test and a liquid electrolyte test; the clamping module assembly for the liquid electrolyte test comprises an upper electrode plate, a lower electrode plate, an upper insulating plate and a lower insulating plate; the clamping module assembly for the solid electrolyte test comprises a porous carbon material; and different clamping module assemblies are selected according to different test objects. By adopting the design scheme that a modularized assembly is used, the fixture and the method respectively become a general fixture and a general method for testing the conductivity of the electrolyte.

Description

technical field [0001] The invention relates to a test tool in the technical field of electrochemistry and new energy, in particular to a test tool design and a test method for the conductivity or resistivity of solid or liquid electrolytes. Background technique [0002] An electrolyte refers to a compound that can generate free ions itself or can exhibit ion conductivity and conduct electricity under certain conditions (such as being dissolved in a solvent to form a solution or melting at a high temperature). It has been widely valued in electrochemical cells due to its unique ion selectivity. These include electrolyte membranes in energy storage batteries, electrolyzers, ion sensors, and fuel cell electrolytes. For electrolyte materials, electrical conductivity is one of the most important indicators. Because, only in electrochemical cells, high conductivity means high battery output performance, work efficiency and stability, etc. Therefore, for a specific material, it...
