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.

Do lithium-ion batteries have separators?

Separators are an essential part of current lithium-ion batteries. Vanessa Wood and co-workers review the properties of separators, discuss their relationship with battery performance and survey the techniques for characterizing separators.

Can a microporous separator be used for lithium ion batteries?

Development of an Advanced Microporous Separator for Lithium Ion Batteries Used in Vehicle Applications (United States Advanced Battery Consortium, 2018). Xu, H., Zhu, M., Marcicki, J. & Yang, X. G. Mechanical modeling of battery separator based on microstructure image analysis and stochastic characterization. J. Power Sources 345, 137–145 (2017).

What role does characterization play in the evolution of lithium-ion separator technology?

Current and emerging characterization techniques will play an important role in guiding this evolution in separator technology. Separators are an essential part of current lithium-ion batteries.

Why do lithium ion separators have pore space?

The electrolyte-filled pore space of the separator membranes allows transfer of lithium ions from the negative porous electrode (anode) to the positive porous electrode (cathode) during discharge and back again during charge, while preventing short circuits between the positive and negative electrodes.

Should lithium ion separators evolve with lithium-ion technology?

Innovation in separator technology — guided by experimental characterization, simulation and analysis — is needed to ensure that separators evolve with lithium-ion technology that is placing new demands on separators and electrolytes 13, 88.
