The permeability of the battery diaphragm is mainly for oxygen, and it needs to reach a certain range to meet the requirements of use. The permeability, surface density, percentage of alkali absorption and other parameters of the diaphragm are interrelated. If the diaphragm is very permeable, the surface density of the diaphragm will be reduced, which will have a certain impact on the performance of the battery. However, if the other parameters are within the ideal range, and the permeability of the diaphragm is not good, it will affect the performance of the battery, so it is necessary to detect the permeability of the diaphragm.
