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.
Separator, a vital component in LIBs, impacts the electrochemical properties and safety of the battery without association with electrochemical reactions. The development of innovative separators to overcome these countered bottlenecks of LIBs is necessitated to rationally design more sustainable and reliable energy storage systems.
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.
In fact, mechanical, thermal and electrochemical effects occurring in the lithium-ion cell have an ongoing impact on the separator. The separator structure, its chemical composition and the electrolyte composition all impact how a separator will respond to the dynamic processes occurring in a cell.
Although separator is an inactive element of a battery, characteristics of separators such as porosity, pore size, mechanical strength, and thermal stability influence the ion transport, cycle life, performance, and safety of the batteries . Thus, the separator represents one of the key components in LIBs.
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 .
