Automotive PE partition series
This model of separator is double-sided with ribs, with thicker ribs on the front and thinner ribs on the back. The spacing between the ribs is reduced compared to the first conventional type, and the corresponding number of ribs is increased. The increased number of ribs provides more space for the plates and space for the free electrolyte, and also provides pressure for the electrodes to maintain contact with the separator; at the same time, the increased number of ribs can prevent lead powder from falling off the plates to the bottom of the battery, causing short circuits. However, compared to the previous single-sided rib type, the relative resistance of this separator is slightly higher. In addition, after multiple assembly tests by battery manufacturers, it has been found that this multi-rib separator is more conducive to automatic wrapping machines, greatly improving production efficiency, reducing the defect rate during plate wrapping, and saving costs for manufacturers to a certain extent.

产品描述
PE Separator Series for Automotive
This model separator is double-sided ribbed, with coarse ribs on the front and fine ribs on the back. The spacing between the ribs is reduced compared to the first regular type, and the corresponding number of ribs is increased. The increased number of ribs provides more space for the plates and space for the free electrolyte, and also provides pressure for the electrodes to maintain contact with the separator; at the same time, the increased number of ribs can prevent lead powder from falling to the bottom of the battery to a certain extent, causing short circuits. However, compared to the previous single-sided ribbed type, the relative resistance of this separator will be slightly larger. In addition, after repeated assembly tests by battery manufacturers, it has been found that this multi-ribbed separator is more conducive to automatic packaging machines, greatly improving production efficiency, reducing the defect rate during plate packaging, and saving costs for manufacturers to a certain extent.
