Lithium-ion battery separators: Recent developments and state
Traditionally, battery separators are chemically and electrochemically inert. However, a new conceptual framework for Li-ion battery design proposes that separators should actively participate in the cell chemistry to enhance performance and enable additional features.

G. Mechanical modeling of battery separator based on microstructure image analysis and stochastic characterization. J. Power Sources 345, 137–145 (2017).
- Do lithium-ion batteries have a separator membrane?
- 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.
- What is a battery separator?
- The battery separator is one of the most essential components that highly affect the electrochemical stability and performance in lithium-ion batteries. In order to keep up with a nationwide trend and needs in the battery society, the role of battery separators starts to change from passive to active.
- Are battery separators active or passive?
- In order to keep up with a nationwide trend and needs in the battery society, the role of battery separators starts to change from passive to active. Many efforts have been devoted to developing new types of battery separators by tailoring the separator chemistry.
- Are ceramic separators good for lithium sulfide batteries?
- The ceramic separators not only exhibit strong chemical affinity for polysulfides but also possess high mechanical strength to resist the lithium dendrites, resulting in excellent long-term cycling stability of Li–S batteries.
