Synergistic Cation–Anion Regulation of Polysulfides by Zwitterionic Polymer Binder for Lithium–Sulfur Batteries

Advanced Functional Materials, 2022
The practical application of lithium–sulfur (Li–S) batteries is gravely hampered by the dissolution and shuttle of lithium polysulfides. Herein, a zwitterionic polymer binder with both lithiophilicity and sulfophilicity is skillfully designed to realize ...

Polysulfide Tandem Conversion for Lithium–Sulfur Batteries

Small
AbstractThe 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 ...

A Sustainable Multipurpose Separator Directed Against the Shuttle Effect of Polysulfides for High‐Performance Lithium–Sulfur Batteries

Advanced Energy Materials, 2022
The success of lithium–sulfur batteries will reduce the expected Co, Ni resource challenges from the wide adoption of lithium‐ion batteries. Unfortunately, the shuttle effect of soluble polysulfides brings many problems.

Suppressed Shuttle via Inhibiting the Formation of Long‐Chain Lithium Polysulfides and Functional Separator for Greatly Improved Lithium–Organosulfur Batteries Performance

Advanced Energy Materials, 2019
The development of lithium–sulfur batteries is limited by the poor conductivity of sulfur cathodes and soluble long‐chain lithium polysulfides (LPSs), which cause the low utilization of sulfur and the aversive shuttle effect, and further, give rise to ...

Three dimensional porous SiC for lithium polysulfide trapping

Physical Chemistry Chemical Physics, 2018
A 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.
