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.
Separators are the battery heart as they are critical to safety and performance. The role and challenges of separators in lithium/sodium-ion batteries are discussed. The state-of-the-art fundamental requirements of separators for LIBs/NIBs are outlined. Recent advances in the development of hybrid polyethylene separators are summarized.
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.
Therefore, the two safety guarantee properties of the composite separator greatly enhance the safety and service life of the battery, which allows the application of lithium batteries to be further improved in the application scenario and application scale.
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.
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 .
