Why is regulating the membrane porous structure important for lithium rechargeable batteries?

As the vital roles such as electrodes, interlayers, separators, and electrolytes in the battery systems, regulating the membrane porous structures and selecting appropriate membrane materials are significant for realizing high energy density, excellent rate capability, and long cycling stability of lithium rechargeable batteries (LRBs).

Which microporous membrane is used in lithium-ion battery separator?

The polypropylene (PP) microporous membrane has been widely used in lithium-ion battery (LIB) as a separator. Compared with polyethylene (PE) microporous membrane, it shows a higher thermal stability due to its higher melting point.

Why do lithium-ion batteries have a porous membrane?

More importantly, the asymmetric porous structured membrane with a dense layer can act as an active material and current collector, avoiding the use of separate current collectors, even conductive agents and binders in lithium-ion battery, which is beneficial for superior electrochemical performances in terms of high reversible capacity.

Does boehmite-coated microporous membrane improve electrochemical performance of lithium-ion batteries?

Xu, R., Lin, X., Huang, X. et al. Boehmite-coated microporous membrane for enhanced electrochemical performance and dimensional stability of lithium-ion batteries.

Can a porous membrane inhibit the shuttle of polysulfide in lithium-sulfur batteries?
