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.
For more than 85 years, Daramic is the world's leading manufacturer and supplier of battery separators to the lead acid battery industry. As the inventor of the first polyethylene separator, Daramic delivers the products our customers need today - and innovate the solutions that serve their needs tomorrow.
A battery separator is a polymeric membrane placed between the positively charged anode and negatively charged cathode to prevent an electrical short circuit. The separator is a microporous layer that is moistened by the electrolyte that acts as a catalyst to increases the movement of ions from one electrode to the other electrode.
The polyolefin separator material used in lithium battery is shown below. At present, the separators are developed from various types of materials such as cotton, nylon, polyesters, glass, ceramic, polyvinyl chloride, tetrafluoroethylene, rubber, asbestos, etc...
At present, the separators are developed from various types of materials such as cotton, nylon, polyesters, glass, ceramic, polyvinyl chloride, tetrafluoroethylene, rubber, asbestos, etc... In conditions like rising in temperature, the pores of the separator get closed by the melting process and the battery shuts down.
Later, in the year 1947, the sealed nickel-cadmium was developed and in the 1970s the maintenance-free lead-acid batteries were introduced. In these designs, the electrolytes will be absorbed into the porous separator that is compressed against the electrodes so that they can achieve the required chemical reaction.

Technology
Historically, lead acid battery separators have included cellulose, polyvinyl chloride, organic rubber, and polyolefins. Today, most flooded lead acid batteries utilize "polyethylene separators" — a misnomer because these microporous separators require large amounts of precipitated silica to be acid-wettable.
US4440838A
An improved battery separator for lead-acid battery cells has low resistance to electrolyte ion transfer and can assist in holding paste in contact with a grid of an electrode plate during chemical reactions of the cell. The separator is formed by depositing an improved wetting composition to a polyolefin substrate comprised of entangled microfibers.
