Lithium-ion batteries (LIBs) have been widely applied in electronic communication, transportation, aerospace, and other fields, among which separators are vital for their electrochemical stability and safety.
The classification of separator in a lithium ion battery depends on physical as well as chemical behavior. These may be woven, molded, nonwoven, bonded, micro porous, paper-based, or laminated types. Nowadays, microporous polymeric films or nonwoven fabrics are being utilized for making separators for lithium ion batteries.
Provided by the Springer Nature SharedIt content-sharing initiative Lithium-ion batteries (LIBs) with liquid electrolytes and microporous polyolefin separator membranes are ubiquitous. Though not necessarily an active component in a cell, the separator plays a key role in ion transport and influences rate performance, cell life and safety.
On the other hand, the interplay between lithium metal and cellulose prevents the formation of high surface area lithium, reducing the degradation of the lithium metal anode, which makes this separator promising battery material with high energy density lithium-sulfur and other lithium metal batteries.
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.
