Lithium battery separator mechanical properties test machine ASTM D882-10 ASTM F1306 ASTM D3763-10 GBPI GBH-2 Tester Provide complete mechanical properties test of lithium battery separator, mainly including separator tensile strength, elongation, puncture strength, peeling strength (coating composite film), etc. Lithium battery separator tensile test The main function of the separator is to separate the positive and negative electrode materials of the battery, prevent the contact between the two poles and short circuit, and at the same time enable electrolyte ions to pass through it. Under the premise of the thinness as thin as possible, it is necessary to ensure that it has a certain physical and mechanical strength to meet the various environments in the production and use of the diaphragm. Because in the battery production process, the separator needs to be curled with the positive and negative electrode materials to form our common cylindrical or pouch battery, sufficient tensile strength can ensure that the separator does not break during the curling process and is smoothly formed.
