China produces around 80% of the world’s separators. Out of these, 70% are wet process separators and 30% are process separators. As NMC battery are targeting higher energy density, manufacturers are mostly using wet separators. This is due to wet separators are 30%-40% thinner than dry separators, it can save more space for other components.
Lead acid batteries pose the following challenges to a separator. Both anode and cathode are subject to shape change and possible embrittlement, so the separator must be compliant enough to accommodate this type of change while also preventing material crossover.
Methodologies to fabricate battery separators are sorted into two methods: (1) wet method and (2) dry method . The separator prepared by the wet method has interconnected pores through the entire area (Figure 2 a). On the other hand, the separator fabricated by dry method has plenty of slit-like pores (Figure 2 b).
The wet process is widely used for manufacturing battery separators, especially polymeric materials. Polymer Solution Preparation: The first step in the wet process involves preparing a polymer solution. The selected polymer, such as polyethylene (PE) or polypropylene (PP), is dissolved in a suitable solvent to create a homogeneous solution.

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.
