An unusual delamination phenomenon on three kinds of lithium‐ion battery separators was investigated in this study, which is closely associated with the compression resistance of the separator.
Lithium-ion batteries are widely used in digital products, electric vehicles, and energy storage systems due to their high energy density and long cycle life [].The separator, as a key component of lithium-ion batteries, serves two fundamental functions []: (1) barrier function, isolating the positive and negative electrodes to prevent short circuits; and (2) ion permeability,
Located between the anode and cathode of the battery, it prevents physical contact between the electrodes, while the separator facilitates the transfer of ions in the battery. It can affect key properties such as capacity, cycle performance, and charge-discharge current density of lithium batteries.
As a vital part of lithium-ion batteries (LIBs), the separator is closely related to the safety and electrochemical performance of LIBs. Despite the numerous membranes/separators available commercially, their thermal stability and service life still severely limit the efficiency and reliability of the battery.
Although the separator is not involved in the electrochemical reaction of lithium ion batteries, it plays the roles of isolating the cathode/anode and uptaking the electrolyte for Li + ions transport, and therefore directly affects the safety and electrochemical properties of lithium ion batteries.

SiO 2 chemically grafted on a PE separator improves the adhesion strength, thermal stability (<5% shrinkage at 120 °C for 30 min), and electrolyte wettability as compared with the physical SiO 2 coating on a PE separator .
Huang et al. designed a multi-layer structural separator to prevent the “shuttle effect” of soluble polysulfides, and therefore extended the cycling life of battery [ 34 ]. The lithium metal anode and silicon anode have the problems of serious volume expansion, unstable SEI film and lithium dendrites.
The battery using this separator achieved high cycle stability with a capacity retention of 82.9% after 2000 cycles with a capacity decay of around 0.008% per cycle and a discharge capacity of around 171 mA h g −1 under a current density of 300 mA g −1 [ 148] ( Fig. 5 c). 4.6.
