Enhancing Sulfur Redox Kinetics of Carbon‐Supported Cobalt Diselenide Electrocatalysts via an Anion‐Doping Strategy

ChemElectroChem, Volume 13, Issue 12, 17 June 2026.
This work presents an anion‐doping strategy to regulate the structure and electronic properties of CoSe2 electrocatalysts through partial substitution of Se by S species. The optimized CoSeS electrocatalyst exhibits enhanced LiPSs adsorption and accelerated redox conversion for high‐performance Li–S batteries. The growing demand for high‐energy‐density

Free‐Standing Binder‐Free Cellulose‐Based MoS2@C@CNFs Electrodes for Lithium–Sulfur Batteries

ChemElectroChem, Volume 13, Issue 12, 17 June 2026.
A novel free‐standing and binder‐free hierarchical MoS2@C@CNFs architecture is successfully fabricated as an effective sulfur host for high‐performance lithium–sulfur batteries. The unique hierarchical synergistic structure provides rapid electron/ion transport and strong physical and chemical adsorption toward polysulfides.

Monitoring Redox Pathways and Performance Limitations in Lithium‐Sulfur Batteries Using In Situ 7/6Li and 33S NMR Spectroscopies

Angewandte Chemie, Volume 138, Issue 24, 8 June 2026.
Lithium‐sulfur (Li‐S) batteries contain various NMR‐active nuclear isotopes, including 7Li, 6Li and 33S, which are sensitive to the different chemical reactions that occur during battery cycling. Herein, we use a combination of lithium and sulfur operando NMR spectroscopy to provide new insights at the molecular level, fundamental understanding being ...

ZnO/ZnSe/rGO heterostructure composite material modified separator for lithium⁃sulfur batteries and its electrochemical performance study

四川大学学报. 自然科学版
The commercial application of lithium-sulfur batteries has long been limited by the “shuttle effect” of polysulfides and their slow conversion kinetics.
