• Elucidating the Discharge Behavior of Aqueous Zinc Sulfur Batteries in the Presence of Molybdenum(IV) Chalcogenide Catalyst: The Criticality of Interfacial Electrochemistry

  ACS Applied Materials & Interfaces · 2024-11-22 · 5 citations

  articleOpen accessCorresponding

  The aqueous zinc–sulfur battery holds promise for significant capacity and energy density with low cost and safe operation based on environmentally benign materials. However, it suffers from the sluggish kinetics of the conversion reaction. Here, we highlight the efficacy of molybdenum(IV) sulfide (MoS2) to reduce the overpotential of S-ZnS conversion in aqueous electrolytes and study the discharge products formed at the solid–solid and solid–liquid interfaces using experimental and theoretical…

• Understanding Electrochemical Sulfur-Based Phase Evolution via Complementary Insight from <i>Operando</i> Spatially Resolved X-ray Diffraction and X-ray Absorption Spectroscopy

  The Journal of Physical Chemistry Letters · 2025-10-03

  article

  Lithium/sulfur batteries are emerging as promising candidates for use in large-scale energy storage, but practical challenges, including insufficient power density and polysulfide shuttling, remain. This work presents the first use of operando energy dispersive X-ray diffraction (EDXRD) to monitor Li/S electrochemistry within a liquid electrolyte. Complementary operando synchrotron-based EDXRD, X-ray absorption spectroscopy (XAS), X-ray powder diffraction (XPD), and ex situ laboratory Raman anal…
