A battery separator is a polymeric membrane placed between the positively charged anode and negatively charged cathode to prevent an electrical short circuit. The separator is a microporous layer that is moistened by the electrolyte that acts as a catalyst to increases the movement of ions from one electrode to the other electrode.
The major role of the battery separator is to physically isolate the anode from the cathode while allowing mobile Li-ions to transport back and forth . Unfortunately, two technical challenges associated with separator puncture and significant thermal shrinkage of polymer separators threaten the overall safety of batteries.
For example, consider a three-layered separator with a PE battery separator material sandwiched between two layers of Polypropylene - PP Separator. The PE layer will melt at a temperature of 130°C and close the pores in the separator to stop the current flow; the PP layer will remain solid as its melting temperature is 155°C.
From the 2000s the large-sized industrial batteries started using triple-layered separators that increase the reliability of separator by using Polypropylene Separator material and improve the thermal shutdown when there is a temperature rise in multi-cell configurations.
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. Many efforts have been devoted to developing new types of battery separators by tailoring the separator chemistry.
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 .
