As one of the essential components of batteries (Fig. 1 a), the separator has the key function of physical separation of anode and cathode and promotes the transmission of ionic charge carriers between electrodes . The mechanical strength and thermal stability of the separator are the basic guarantees of lithium batteries’ safety.
The mechanical strength and thermal stability of the separator are the basic guarantees of lithium batteries’ safety. At the same time, the separator’s high porosity and electrolyte wettability are necessary conditions for the high electrochemical performance of lithium batteries . Fig. 1. (a) Schematic diagram for lithium battery.
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.
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 .
In addition, as another important development trend of battery separators, smart separators are receiving increasing attention. Smart separators can monitor the operating status of batteries in real time, including the transmission of lithium ions and temperature changes in batteries.
These separators primarily consist of inorganic materials, with or without the addition of polymeric binders. Inorganic separators can significantly enhance the high-temperature tolerance of batteries, maintaining structural stability of the separators even at temperatures above 1000 °C.
