Microporous battery separator
What is a battery separator? Battery Separators are microporous diaphragms placed between the negative and positive plates of lead-acid batteries to prevent any contact between them to avoid internal short circuit but at the same time allow free circulation of the electrolyte. This kind of battery separator has a maximum pore size of less than 50-micron meter and lower electrical resistance of less than 0.16 ohm/cm sq. PVC battery separators are uniform in quality, free from holes, broken corners, splits, embedded foreign material, surface rupture, physical defects, etc. PVC battery separator have a very low electrical resistance which reduces internal loss saving on electric energy and improving battery performance.
Their high porosity in the PVC battery separator ensures easy diffusion of electrolyte and movement of ions guaranteeing battery performance even at high discharge rates. Being completely non-reactive to acids, active metals and emitted gases, It enhances the active life of the lead-acid battery and is an ideal choice for Tubular Gel Batteries with a designed battery life of 15 years – PVC Battery Separator will not disintegrate unlike some other types of battery separator. Because of these tremendous benefits, PVC battery separator are exclusively used in Plantè Batteries, Tubular Gel Batteries, Flooded OPzS cells and Flooded Nickel Cadmium Cells.

What is the purpose of separator in a lead-acid battery?
The ideal situation inside a lead-acid battery is to have no separator at all! Since, in that case there would be no internal resistance! However, that would not be possible as the plates would short. The purpose of the battery separator is to create a barrier between the two electrodes & yet allow the free flow of electronic ions between them to keep the reaction happening.
How to test the porosity of a battery separator?
Determination of percentage of volume porosity of battery separator
A-1: Reagents: Distilled water
A-2: Procedure: Exactly cut 127 mm long x 19 mm wide using scissor. Stack 5 strips and fasten them together by wrapping a length of copper wire around one end. Fill the graduated cylinder with approx. 85ml of the D.M water, record this volume(A). immerse the strips in the liquid, shake the strips within the cylinder a few times to remove trapped air, place the stopper loosely on the top of the cylinder and let stand for 10 minutes. After the 10 min stand, record the increased volume of liquid (B).
The volume of the solid material is the increase in the volume of liquid, that is, B-A. Remove the stopper and withdraw the strips from the liquid. Shake the strips lightly at the top of the cylinder to allow any excess water adhering to the surface of the sample to drain back into the cylinder. Record the volume of the liquid remaining in the cylinder C. This volume will be less than that of the original starting volume. Since we have extracted with the sample quantity of the liquid retained in the microporous material. This decrease in volume (A-C) represents the volume of the pores.
A-3. Calculation: % of Volume porosity = A – C X 100
