Ideally, NM should be close to one, while the typical values of the NM for Li-ion battery separators range from 5 to 15. Besides the development of solid electrolyte interphase (SEI) on the electrode particle surface, the compatibility between the separator and the electrodes can also change the cell resistance.
The battery separator is one of the most essential components that highly affect the electrochemical stability and performance in lithium-ion batteries. In order to keep up with a nationwide trend and needs in the battery society, the role of battery separators starts to change from passive to active.
The minimum tensile strength of the separator with a thickness of 25 µm is 98.06 MPa. This value usually occurs during the battery assembly , . In addition, the separator must also withstand punctures due dendrite that may formed during battery usage. ... The trend of using electric vehicles is increasing.
It is crucial to obtain an in-depth understanding of the design, preparation/ modification, and characterization of the separator because structural modifications of the separator can effectively modulate the ion diffusion and dendrite growth, thereby optimizing the electrochemical performance and high safety of the battery.

Recently, much effort has been devoted to the development of battery separators for lithium-ion batteries for high-power, high-energy applications ranging from portable electronics to large-scale energy storage for power grids.
As a key component of LIBs, the separator plays a crucial role in sequestering the electrodes, preventing direct contact between the positive and negative electrodes, and allowing the free passage of lithium ions in the electrolyte. Additionally, the separator is also crucial for ensuring the safe operation of the batteries.
