The separator is a key component of lithium-ion batteries. It plays a crucial role in battery safety, serving as one of the most effective measures against internal short circuits.Separator failure is a direct cause of the thermal runaway and can be specifically divided into three categories: puncture, melting, and thermal shrinkage.
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.

A high safety separator is essential to improve the safety of lithium-ion batteries. This review summarizes its performance requirements and preparation methods. All the separator requirements have a synergistic effect on the electrochemical performance, safety, and scalability of lithium-ion batteries.
Li-ion battery separators may be layered, ceramic based, or multifunctional. Layered polyolefins are common, stable, inexpensive, and safe (thermal shutdown). Ceramic oxides reduce shrinkage and particle penetration and improve wetting. Chemically active multifunctional separators may trap, attract, or dispense ions.
As the ‘third electrode’ material in batteries, the separator is a thin film with a microporous structure positioned between the positive and negative electrodes. Its primary function is to prevent direct contact between the electrodes while facilitating the normal transport of Li + ions and insulating electrons [3, 39, 40].
Real-World Implementations Across Diverse Sectors
In order to keep up with the recent needs from industries and improve the safety issues, the battery separator is now required to have multiple active roles [16, 17].Many tactical strategies have been proposed for the design of functional separators [10].One of the representative approaches is to coat a functional material onto either side (or both sides) of …
