Learn MoreTo meet the demands of high-performance batteries, the separator must have excellent electrolyte wettability, thermotolerance, mechanical strength, highly porous structures, and ionic conductivity. Numerous nonwoven-based separators have been used in LIBs due to their high porosity and large surface-to-volume ratios.
As a critical component of lithium-ion batteries (LIBs), separators play a pivotal role in determining their performance and safety. However, the widely use polyolefin separators in commercial LIBs have certain limitations, such as poor affinity with electrolyte and low thermal stability.
Currently, the most widely used separators in lithium battery systems are the porous polyolefin membranes, such as polyethylene (PE), polypropylene (PP) and their blends (PE-PP), which can meet the requirements of low cost, good flexibility, relatively high mechanical strength, and thermally closed porous structure [1, 4].
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.
