Separators in Lithium-ion (Li-ion) batteries literally separate the anode and cathode to prevent a short circuit. Modern separator technology also contributes to a cell’s thermal stability and safety. Separators impact several battery performance parameters, including cycle life, energy and power density, and safety.
Huang et al. designed a multi-layer structural separator to prevent the “shuttle effect” of soluble polysulfides, and therefore extended the cycling life of battery [ 34 ]. The lithium metal anode and silicon anode have the problems of serious volume expansion, unstable SEI film and lithium dendrites.
Although the separator is not involved in the electrochemical reaction of lithium ion batteries, it plays the roles of isolating the cathode/anode and uptaking the electrolyte for Li + ions transport, and therefore directly affects the safety and electrochemical properties of lithium ion batteries.
These modern separators prevent short circuits, enhance ion conduction, and provide thermal stability. They are now essential in various applications, from lithium-ion and lead-acid batteries to electric vehicles and portable electronics. The performance, safety, and longevity of a battery largely depend on the quality of its separator.
