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

Angewandte Chemie, EarlyView.
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 ...

Sustainable Carbon Fibers Enable Stable Long‐Term Lithium Metal Deposition for Prospective Zero‐Excess Lithium Metal Batteries

Advanced Energy Materials, EarlyView.
This work presents lightweight, lignin‐derived carbon fiber current collectors that enable controlled lithium deposition. Structural defects and intermediate‐sized pores stabilize pre‐nucleation quasi‐metallic lithium clusters, promoting uniform lithium plating and stripping.

Solvent‐Induced Covalent Bond Softening Boosts Battery Voltage

Angewandte Chemie, EarlyView.
The strong attractive interaction between the nucleophilic center of the solvent and the electrophilic region of the covalently bonded cathode fragment triggers charge transfer. This results in the electron population in the antibonding orbital of the covalent bond, leading to bond weakening and elongation, and consequently increasing the cathode ...

Liquid‐Catalyst‐Activated Sparingly Solvating Electrolytes for Low‐Temperature Potassium‐Sulfur Batteries

Advanced Energy Materials, EarlyView.
This study develops a novel sparingly solvating electrolyte for potassium–sulfur batteries, utilizing tetrahydrofuran (THF) to induce an anion‐dominated solvation structure that eases polysulfide shuttling and forms an inorganic‐rich solid–electrolyte interphases (SEI). Dimethyl diselenide (DMDSe) accelerates quasi‐solid‐state transformations, reducing
