3mm PAN fiber for battery separators

Adding 3mm polyacrylonitrile short fibers to the positive and negative electrode paste can significantly enhance the strength of the electrode plate, improve the binding force between the active materials and the grid, inhibit the shedding of the active materials during recycling, and extend the battery life.

Benefits                                             

1. The length is neat and standard, with excellent dispersion and processability.

2. The single fiber has fine fineness, high strength, and a large number of fibers added with       the same weight. The mesh structure is more stable, significantly reducing plate cracking, chipping, and powder removal.

3. Good temperature resistance, suitable for the high temperature at the instant of adding      acid to the paste and the high temperature requirements during the drying process, without softening and deformation.

4. Good acid resistance, chemical and electrochemical corrosion resistance, anti-aging, normal scrapped battery plate. After anatomical inspection, the fiber is basically unchanged.
