Monitoring Redox Pathways and Performance Limitations in Lithium-Sulfur Batteries Using In Situ ^7/6Li and ³³S NMR Spectroscopies. [PDF]

Angew Chem Int Ed Engl
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 ...
