DSC calorimeter GB-DSC100A

DSC Differential Scanning Calorimeter to test Thermal Performance of Battery Packaging Separator Standard U L 2591, INASA TM 2010-2l6099, etc As an important component of lithium batteries, the separator is of great significance to block electrons, prevent short circuits and ensure internal ion penetration to make the battery run efficiently, stably and safely. Although the separator itself does not undergo any electrochemical reactions, its structure and performance affect the interface structure and internal resistance of the battery, which in turn affects the overall capacity, charge and discharge current density, cycle performance, and safety of the battery. Therefore, the comprehensive performance of the battery can be effectively improved through the analysis, testing and regulation of various performance parameters of the lithium battery separator. Referring to the regulations of the United States Advanced Battery Consortium (USABC) on the performance parameters of lithium-ion battery separators, the performance of battery separators can be roughly divided into four aspects: physical and chemical properties, mechanical properties, thermal properties and electrochemical properties. Among them, physical and chemical properties include thickness, porosity, average pore size and pore size distribution, air permeability, tortuosity, wettability, liquid absorption rate, and chemical stability. Mechanical properties mainly include 3 parameters of puncture strength, mixed puncture strength and tensile strength. Thermal properties include 3 parameters of thermal closure temperature, melting rupture temperature and thermal shrinkage rate.
