A lead acid battery separator is a material that is placed between the positive and negative electrodes of a lead acid battery. The separator material allows for ionic communication between the electrodes while preventing electrical contact between them. This prevents shorts and maximizes the efficiency of power transfer in the battery.
The nickel-based batteries are built with porous polyolefin films, nylon or cellophane separators, whereas the sealed lead acid battery separator uses a separator called AGM Separator (Absorbed Glass Mat) which is a glass fiber mat soaked in sulfuric acid as a separator.
The right separator material will vary depending on the specific application or requirements of the battery. A Pb-Ca separator is a type of lead acid battery separator that uses calcium as the primary cation. The Ca/Pb ratio is typically 2:1. Ca/Pb separators are used in both automotive and industrial lead acid batteries.
While PE and GF are the most common separator materials used in lead acid batteries, other materials such as polypropylene (PP), cellulose, and fluoropolymers can also be used. PP is similar to PE in terms of chemical resistance and dielectric strength, but it has a lower melting point.
In alkaline batteries, the separators used are either regenerated cellulose or microporous polymer films. Lithium batteries with organic electrolytes mostly use microporous films. The type of separator can be divided into the following groups: There are a number of things that can cause an internal short circuit within a battery cell.
All organics are decomposed with time in the hostile environment of a lead–acid cell. The separator should be as stable as possible, at least as long as the expected battery life, which can be up to 30 years in stationary batteries. Whereas silica is absolutely stable, this is not the case with the organics, even when they are macromolecules.
