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 a battery separator?

There are many important components in the LiB, one of which is a separator that serves to block short circuits between the anode and cathode of the battery while providing a way for ion exchange to continue. This article summarizes important information related to battery separator technology.

What is the thermal shrinkage of a Lithium Ion Separator?

Thermal shrinkage A separator with low melting temperature tends to melt and shrink, which causes pore blockage and eventually terminates the ion transport between the electrodes . Thus, a separator with a shrinkage of <5% for 60 min at 200 °C has typically been desirable for LIBs .

Why is a battery separator important?

Although separator is an inactive element of a battery, characteristics of separators such as porosity, pore size, mechanical strength, and thermal stability influence the ion transport, cycle life, performance, and safety of the batteries . Thus, the separator represents one of the key components in LIBs.
