The mechanical strength and thermal stability of the separator are the basic guarantees of lithium batteries’ safety. At the same time, the separator’s high porosity and electrolyte wettability are necessary conditions for the high electrochemical performance of lithium batteries . Fig. 1.

As one of the essential components of batteries (Fig. 1 a), the separator has the key function of physical separation of anode and cathode and promotes the transmission of ionic charge carriers between electrodes . The mechanical strength and thermal stability of the separator are the basic guarantees of lithium batteries’ safety.
Separators for the lithium battery market are usually manufactured via a “wet” or “dry” process. In the “dry” process, polypropylene (PP) or polyethylene (PE) is extruded into a thin sheet and subjected to rapid drawdown.
It allows ions to migrate during the charge-discharge process [5, 6], and the separator does not directly contribute to any battery reaction. The conventionally LIBs separators used on a large scale are polyolefin separators, which are polyethylene (PE) and polypropylene (PP) or their multilayer formations [7, 8].
ENTEK manufactures lithium-ion separators using a “wet” process. The molecular weight distribution of polyethylene, the percentage and type of plasticizer, extraction and drying conditions, biaxial stretch ratios, and annealing temperature are all factors that impact the final structure and properties of the separator.
After delivery to the lithium battery manufacturer, separator rolls are loaded onto an un-winding station along with individual rolls of cathode and anode. Two separator rolls are required so that the separator is interspersed between the anode and cathode while all 4 layers are wound around a pin to form a “jellyroll”.
