Effect of AGM Separator Properties on the Performance of Sealed Lead-Acid Batteries
Effect of AGM Separator Properties on the Performance of Sealed Lead-Acid Batteries
Including the uniformity of basis weight and thickness, resilience and compressibility, porosity and acid absorption, pore size, electrical resistance, impurities, etc. The following points are indicated:
(1) The basis weight and uniformity of the separator are the main reasons affecting the uniformity of battery capacity;
(2) The resilience and compressibility of the separator are the guarantee for the tight assembly of the battery, and also the guarantee for the good adhesion between the separator and the electrode plate in the battery;
(3) The porosity and acid absorption capacity of the separator are the guarantee of battery capacity, service life and high-current discharge performance;
(4) The pore size of the separator reflects the ability of the separator to prevent the penetration of lead dendrites;
(5) The resistance of the battery separator directly affects the low-temperature start-up performance and high-current discharge performance of the battery;
(6) Impurities in the separator are the direct cause of self-discharge of the battery.
