Lead acid battery separator materials have progressed significantly over the history of this workhorse chemistry and is a good indicator of the arrow of progress of the entire field. The first lead acid separators were natural rubbers that had moderate porosity (∼55–65 %) with more sizes on the order of 1–10 μm. These separators were on the order of 500 μm thick.

Typical separators used for lead–acid batteries throughout the world are listed in Table 2, together with the battery characteristics. Among these, the leaf-type SPG separator and the pocket-type PE separator are used in Japan according to the battery application, battery usage, and system requirements. The SPG separator is used together with a glass mat in
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. Silica is responsible for the separator''s electrical properties; polyethylene is responsible for the separator''s mechanical properties. The

The evolution of separators in lead-acid batteries can be attributed to two main breakthroughs. First, in the late 19th century, Camille Alphonse Faure improved upon Planté''s design by implementing a lead grid lattice, which increased the battery''s effective surface area. This modification significantly enhanced the battery''s capacity and performance. The second

During the winding of the spiral wrap construction considerable mechanical pressure is applied to the cathode–separator–anode interface. Any loose particle could be forced through the separator and short the cell. The mix penetration strength should be at least 100 kgf/mil for separators used in lithium-ion cells. 11.
Very little has been done in incorporating the effect of physical and chemical properties of separators on the performance and safety of batteries. This is also because the microstructure of separators and their effect on transport properties in batteries are generally known only qualitatively.
According to the patent, the separator has microporous regions of PE and PP. On heating in an oven, the impedance of the separator increases near the melting point of PE and the impedance remains high until beyond the melting point of PP. However, battery performance data have not been presented.
It is evident that a wide variety of separators are available, and that they are critical components in batteries. In many cases, the separator is one of the major factors limiting the life and/or performance of batteries. Consequently, development of new improved separators would be very beneficial for the advanced high capacity batteries.
Fan and White chose a α value of 2.5 for separators in NiCd batteries and Doyle et al. used 3.3 for lithium-ion batteries. Arora et al. measured the value as 2.4 for PVdF-based separators by measuring the separator and electrolyte conductivity at different salt concentration.
The instrument can measure a number of characteristics of battery separators such as size of the pore at its most constricted part, the largest pore size, pore-size distribution, permeability, and envelope surface area . Scanning electron microscopy (SEM) is also used to examine separator morphology.
