Lithium Battery Constant Volume Combustion And Explosion Chamber
Introduction:
The lithium battery constant volume combustion and explosion chamber places the lithium battery or battery module in a specific explosion-proof and enclosed test space. By heating, the battery cell or module is triggered to trigger thermal runaway, and then the test parameters such as gas production volume, gas production rate, pressure, temperature, etc. in the enclosed space are analyzed. At the same time, the gas in the enclosed space can be collected, and chemical analysis instruments can be used to conduct qualitative and quantitative analysis of the composition of the gas.

Necessity of Lithium battery constant volume combustion and explosion chamber:
Thermal runaway is a phenomenon that occurs violently and is highly harmful, with bulging, bloating, expansion, and even explosion processes. There are many factors that cause thermal runaway, including short circuit, high temperature, extrusion, acupuncture, etc. The internal changes of lithium batteries have different effects as the temperature rises. Under high temperatures, the electrolyte, diaphragm, and fluid in the battery are in an unstable state. If they come into contact with oxygen, they may be accompanied by violent combustion, causing a battery explosion, which may cause significant losses to personnel. In the lithium battery constant volume explosion chamber, the safety of the test personnel can be greatly protected. Due to its closed and pressure-bearing structure, the test personnel do not need to directly face the risk of battery cell explosion. At the same time, the whole process of the test sample can be observed in an all-around way through the audition mirror.
