Selection and comparison of separators for lead-acid batteries

The separator is an important component of the battery, not an active substance, and even plays a decisive role in some cases, so how to choose the separator is an important factor affecting the performance of the lead-acid battery, if you want to obtain a high-performance PE separator for lead acid Battery, you can refer to the following points:

1. The chemical stability should be good, and it must be resistant to sulfuric acid corrosion, oxidation and aging

   
   

2.  Good wettability, i.e. it should be able to be quickly soaked with electrolyte sulfuric acid

   
   

3.  No impurities that can leach out harmful to the battery in the sulfuric acid solution

   
   

4. The resistance of immersion in the sulfuric acid solution of the electrolyte should be small

   
   

5. Certain porosity, and the consistency of the pore size should be high

   
   

6. Surface color should be basically the same, cracks and perforations are not allowed
