However, such thick separators come at the expense of less free space for accommodating active materials inside the battery, thus impeding further development of next-generation lithium-based batteries with high energy density.
Separators are indispensable components in lithium-based batteries without being directly involved in the electrochemical reaction of batteries.
There are many important components in the LiB, one of which is a separator that serves to block short circuits between the anode and cathode of the battery while providing a way for ion exchange to continue. This article summarizes important information related to battery separator technology.
The porosity is definitely the basic requirement for separators of lithium-based batteries to transport Li ions. A sufficient amount of liquid electrolyte should be trapped within micro pores and interconnected channels in separator to sustain a high ion conductivity.
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 .
