Why is a lithium ion battery separator important?
The separator is an indispensable component in lithium-ion batteries and sodium-ion batteries and directly affects the electrochemical performance and, especially, safety. It is imperative to develop high-safety separators for rechargeable lithium-ion batteries and sodium-ion batteries.
What are lithium-ion battery separators?
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.
What are the different types of battery separators?
Li-ion battery separators may be layered, ceramic based, or multifunctional. Layered polyolefins are common, stable, inexpensive, and safe (thermal shutdown). Ceramic oxides reduce shrinkage and particle penetration and improve wetting. Chemically active multifunctional separators may trap, attract, or dispense ions.
Can a multifunctional separator be used in a Li-ion battery separator?
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 .
How can a battery separator be improved?
The safety issue, which is a major concern that limits battery applications, could be mitigated by increasing the separator's mechanical strength, thermal stability, and shutting the batteries down below thermal runaway temperature through various functionalization approaches.
