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).
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.
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.

Furthermore, although the porous feature of the membrane meets the requirement of traditional lithium-ion batteries, it cannot inhibit the shuttle of polysulfide in lithium-sulfur batteries.
Functional membranes play different roles in battery systems. For example, compared to a conventional lithium-ion battery membrane, ideal membranes for the Li-S battery should also have the function to block the shuttling of polysulfide and prevent the internal short circuits.
