Journal ArticleDOI
Lithium/Sulfur Cell Discharge Mechanism: An Original Approach for Intermediate Species Identification
Céline Barchasz,Florian Molton,Carole Duboc,Jean-Claude Leprêtre,Sébastien Patoux,Fannie Alloin +5 more
TL;DR: This study proposes a possible mechanism for sulfur reduction consisting of three steps, and investigates the electrolyte composition at different discharge potentials in a TEGDME-based electrolyte.
Journal ArticleDOI
New insights into the limiting parameters of the Li/S rechargeable cell
TL;DR: In this article, the authors investigated the most important limiting parameters of a Li/S cell and concluded that the cell capacity limitation may be linked to dissolution of sulfur material and to passivation of the positive electrode.
Journal ArticleDOI
New insight into the working mechanism of lithium–sulfur batteries: in situ and operando X-ray diffraction characterization
Sylwia Waluś,Céline Barchasz,Jean-François Colin,Jean-Frédéric Martin,Erik Elkaim,Jean-Claude Leprêtre,Fannie Alloin +6 more
TL;DR: This communication presents synchrotron-based in situ XRD studies of structural modifications occurring inside the cell upon cycling, since the active material changes constantly its form between solid and liquid phases.
Journal ArticleDOI
Lithium/Sulfur Batteries Upon Cycling: Structural Modifications and Species Quantification by In Situ and Operando X‐Ray Diffraction Spectroscopy
Sylwia Waluś,Sylwia Waluś,Céline Barchasz,Renaud Bouchet,Renaud Bouchet,Jean-Claude Leprêtre,Jean-Claude Leprêtre,Jean-François Colin,Jean-Frédéric Martin,Erik Elkaïm,Carsten Baehtz,Fannie Alloin,Fannie Alloin +12 more
TL;DR: Dr. S. Waluś, Prof. R. Barchasz, Dr. J-F. Colin, and Prof. J.-C.
Journal ArticleDOI
Electrochemical properties of ether-based electrolytes for lithium/sulfur rechargeable batteries
TL;DR: In this article, the authors investigated the electrolyte effects on electrochemical performances of the Li/S cell, by acting on the solvent composition, and different kinds of solvent structures were investigated by changing the ether/alkyl moieties ratio to vary the lithium polysulfide solubility.
