TL;DR: In this paper, a facile, scalable, and green process to fabricate porous graphene (PG) modified separators for commercially viable lithium-sulfur batteries was reported, in combination with an amphiphilic polymer binder, rendered the engineered functional layer with extraordinary electrical conductivity, high surface area, large pore volume, and appropriate strength of chemisorption to polysulfides.

TL;DR: A thermal exfoliation of metal-organic framework crystals with intrinsic 2D structure into multilayer graphene stacks is reported, which is showcased as suitable model cathode host for unveiling the challenging surface chemistry issue in Li-S batteries.

TL;DR: In this study, quinonoid imine is proposed to anchor polysulfides and to facilitate the formation of Li2 S2 /Li2 S through the reversible chemical transition between protonated state (NH+ ) and deprotonatedstate (N).

TL;DR: In this paper, a bio-inspired beaver-dam-like membrane was proposed as a robust and sulphifilic nest separator for advanced Li-S cells, which was integrated by a continuous polypropylene, a highly electrical conducting network of carbon nanotubes (CNTs), and lithium polysulfide (LiPS)-suppressing adsorbents of magnesium borate hydroxide (MBOH) nanofibers to enhance the redox reaction of LiPS intermediates and retard their migration in a working cell.

TL;DR: In this article, the hierarchical porous γ-AlOOH/γ-Al 2 O 3 microspheres with a specific surface area of 158.6 m 2 g −1, and ca. 92% of which bear a size of 3.0-7.5 µm.
