Lithium-ion battery separators are receiving increased consideration from the scientific community. Single-layer and multilayer separators are well-established technologies, and the materials used span from polyolefins to blends and composites of fluorinated polymers.
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.
Over the last five years, cellulose-based separators for lithium batteries have drawn a lot of interest due to their high thermal stability, superior electrolyte wettability, and natural richness, which can give lithium batteries desired safety and performance improvement.
There are many important components in the LiB, one of which is a separator that serves to block short circuits between the anode and cathode of the battery while providing a way for ion exchange to continue. This article summarizes important information related to battery separator technology.
Multifunctional separators offer new possibilities to the incorporation of ceramics into Li-ion battery separators. 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 .
Ceramic-coated separators and high melting point polymer materials offer some improvement in thermal stability and abuse tolerance for lithium-ion cell separators but, in general, more evaluation is needed to quantify the safety impact of these new separators.
