Quality requirements for partitions

Page view
[Abstract]:
The separator is an important component in the production of batteries. Its advantages and disadvantages directly affect the discharge 
The separator is an important component in the production of batteries. Its advantages and disadvantages directly affect the discharge capacity of the battery and the life of the charge and discharge cycle. Therefore, the selection and research of the battery separator must be taken seriously. The quality requirements of the partitions should generally have the following requirements
 
1. The separator material itself is an insulator, but the separator must have a loose porous structure and can absorb an enlarged amount of the electrolyte solution;
 
2. The chemical stability of the separator is good, and it must be resistant to sulfuric acid corrosion, oxidation and aging;
 
3, the partition should have greater mechanical strength and flexibility, easy to install in production;
 
4, the separator should have good wettability, that is, it should be quickly soaked by the electrolyte sulfuric acid;
 
5. There should be no impurities in the separator that can be leached in the sulfuric acid solution;
 
6, the surface color of the partition should be basically the same, no cracks and perforations are allowed;
 
7. The resistance of the separator immersed in the electrolyte sulfuric acid solution should be small;
 
8. The partition should have a wide range of operating temperatures;
 
9. The partition should have a certain porosity and the consistency of the aperture should be high;
 
10. For flexible partitions, it must have a shrinkage or expansion ratio that meets the requirements;
 
11. It should have good folding resistance to soft partitions;
 
12. The dry thickness and uniformity of the partition should meet the requirements of the index;
