TL;DR: This work reports a different strategy based on an inherently polar, high surface area metallic oxide cathode host and shows that it mitigates polysulphide dissolution by forming an excellent interface with Li2S and provides experimental evidence for surface-mediated redox chemistry.

TL;DR: In this paper, it is shown through a combination of surface spectroscopy and cyclic voltammetry studies that only materials with redox potentials in a targeted window react with polysulfides to form active surface bound polythionate species.

TL;DR: In this paper, the authors investigate cathodes for the Li-S cell comprised of sulfur-imbibed robust spherical carbon shells with tailored porosity that exhibit excellent cycling stability, showing how sulfur fraction (underutilization) and sulfide precipit...

TL;DR: The most highly optimized sulfur-porous carbon nanosphere composite, created using pore-formers to tailor shell porosity, exhibits excellent cycling performance and rate capability.

TL;DR: In this article, a solvent-salt complex with a hydrofluoroether (HFE) co-solvent is proposed for Li-S battery electrolytes, which possess stability against Li metal and viscosities which approach that of conventional ethers, but have the benefit of low volatility and minimal solubility for lithium polysulphides while exhibiting an uncharacteristic sloping voltage profile.
