Separator Shutdown & Break Tester closed cell rupture test machine ART-GMT-35L

It is the first in the industry to measure the ionic impedance of the diaphragm at high temperature, which is used for diaphragm process and battery design improvement and quality monitoring to ensure the safety of the battery. At the same time, the wettability of the diaphragm and electrolyte can be evaluated.
The diaphragm has a microporous structure, through which ions can pass; as the pores of the diaphragm shrink at high temperatures, the ion resistance increases. This process is called closed pores; after the temperature continues to rise, the diaphragm melts and breaks, and the resistance decreases, which is called membrane rupture. A separator with good closed-cell membrane breaking characteristics can improve the safety of lithium batteries, especially greatly reducing the risk of static fires in electric vehicles.
