3. Summary and Outlook The separator is a crucial component in Li-ion batteries with the function of preventing physical contact between the positive and negative electrodes of the battery and stopping internal short while serving as the electrolyte reservoir to enable ionic transport.
The properties of separators have direct influences on the performance of lithium-ion batteries, therefore the separators play an important role in the battery safety issue.
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.
It is crucial to obtain an in-depth understanding of the design, preparation/ modification, and characterization of the separator because structural modifications of the separator can effectively modulate the ion diffusion and dendrite growth, thereby optimizing the electrochemical performance and high safety of the battery.
The Li-ion battery separator is one of the crucial factors affecting fire safety performance since it directly contributes to the thermal stability of the entire battery system. As one of the most important components in Li-ion batteries, the separator is placed between the anode and cathode [ 7 ].
