What are lithium-ion battery separators?

Lithium-ion battery separators are receiving increased consideration from the scientific community. Single-layer and multilayer separators are well-established technologies, and the materials used span from polyolefins to blends and composites of fluorinated polymers.

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.

Why do we need a lithium battery separator?

Separator, a vital component in LIBs, impacts the electrochemical properties and safety of the battery without association with electrochemical reactions. The development of innovative separators to overcome these countered bottlenecks of LIBs is necessitated to rationally design more sustainable and reliable energy storage systems.

How does a Lithium Ion Separator work?

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.

What is an inorganic battery separator?

These separators primarily consist of inorganic materials, with or without the addition of polymeric binders. Inorganic separators can significantly enhance the high-temperature tolerance of batteries, maintaining structural stability of the separators even at temperatures above 1000 °C.

What are smart battery separators?

In addition, as another important development trend of battery separators, smart separators are receiving increasing attention. Smart separators can monitor the operating status of batteries in real time, including the transmission of lithium ions and temperature changes in batteries.
