The battery separator air permeability tester is a device made and produced in strict accordance with the GB T 36363-2018 standard, this instrument adopts electronic intelligent control, the entire test process is completed automatically, the test results can be printed at any time, and it has multi-level authority management, which is a commonly used testing equipment for enterprises.
GB T 36363-2018 Standard Battery Separator Air Permeability Tester Test Principle:
In a laboratory setting, 1At a pressure of 21 kPa, the time required for 100 ml of test gas to pass through a specific area of the battery separator is recorded.
GB T 36363-2018 Standard Battery Separator Air Permeability Tester Test Operation Process:
1. Cut 3 diaphragms at a longitudinal distance of 150 mm on the film roll. The specimen size is 100 mmx100 mm for 100 mm for 100 mm and 100 mm for < 100 mm.
2. The diaphragm is placed in the test head of the air permeability instrument suitable for the test range for air permeability test, and the average of the 3 test results is taken as the air permeability of the diaphragm.
GB T 36363-2018 Standard Battery Separator Air Permeability Tester Application Importance:
1.Improve the safety factor of battery separator.
By using this equipment, the air permeability of the battery separator can be effectively detected to ensure the safety of the battery separator. If the air permeability of the battery separator is not up to standard, the gas in the battery may not be discharged, causing dangerous conditions such as **.
2.Improve the durability of battery separators.
By testing the air permeability of the battery separator, we can find the right battery separator and improve the durability of the battery. If the air permeability is too low, it may lead to the accumulation of gas inside the battery, increase the resistance inside the battery, and reduce the charging and discharging efficiency of the battery. Conversely, if it is too high, it may cause the electrolyte inside the battery to lose too quickly, reducing the cycle life of the battery.
The above content is a detailed introduction to the GB T 36363-2018 standard battery separator permeability tester, the battery separator permeability tester is an important instrument to evaluate the quality of battery separator, through the use of this instrument, the safety and durability of the battery separator can be effectively ensured.
