This model of separator has double-sided ribs, with thick ribs on the front and thin ribs on the front. The spacing between the ribs is reduced compared to the first conventional type, and the corresponding number of ribs increases. The increase in the number of ribs provides more sufficient space for the electrode plate and space for the presence of free state electrolytes, as well as pressure for the electrode to maintain contact with the separator; Meanwhile, an increase in the number of bars can to some extent prevent the lead powder from falling off the electrode plate and causing short circuits at the bottom of the battery. However, compared to the previous single-sided reinforcement, the relative resistance of this type of separator will be slightly higher. In addition, after multiple tests and assembly by battery manufacturers, it was found that this multi rib separator is more conducive to the packaging of automatic packaging machines, greatly improving production efficiency, reducing the scrap rate during the electrode packaging process, and saving costs for manufacturers to a certain extent.
