Polysulfide Tandem Conversion for Lithium–Sulfur Batteries
SmallAbstractThe electrocatalytic conversion of 16‐electron multistep polysulfides is crucial for lithium–sulfur batteries, while it is hard to achieve compatibility between intricate sulfur reduction processes and appropriate catalysts. Herein, a tandem conversion strategy is reported to boost multi‐step intermediate reactions of polysulfides ...

Three dimensional porous SiC for lithium polysulfide trapping
Physical Chemistry Chemical Physics, 2018A series of 3D porous SiC materials with active sp2 hybridized Si atoms have been designed for lithium polysulfide retention in Li–S batteries. The shuttle effect can be effectively depressed by the strong Si⋯S interaction between Li2Sn and the 3D porous SiC hosts.

Two-Stage Solvation of Lithium Polysulfides in Working Lithium–Sulfur Batteries
Journal of the American Chemical SocietyLithium-sulfur (Li-S) batteries are promising in achieving high energy density but inferior in cycling lifespan since Li polysulfides (LiPSs) corrode Li metal anode. Weakening the electrolyte solvating power (ESP) for LiPSs effectively mitigates anodic corrosion but inevitably retards cathodic reaction kinetics.

In Situ Polysulfide Detection in Lithium Sulfur Cells
The Journal of Physical Chemistry Letters, 2018Lithium sulfur batteries promise significant improvements in specific energy compared to Li-ion, but are limited by capacity fade upon cycling. Efforts to improve durability have focused on suppressing the solubility of intermediate polysulfides in the electrolyte.

Carbon Nitride Phosphorus as an Effective Lithium Polysulfide Adsorbent for Lithium–Sulfur Batteries
ACS Applied Materials & Interfaces, 2019Lithium-sulfur (Li-S) batteries are attracting substantial attention because of their high-energy densities and potential applications in portable electronics. However, an intrinsic property of Li-S systems, that is, the solubility of lithium polysulfides (LiPSs), hinders the commercialization of Li-S batteries.
