New insight into the working mechanism of lithium–sulfur batteries: in situ and operando X-ray diffraction characterization
Résumé
In order to improve the electrochemical performances of lithium–sulfur batteries, it is crucial to understand profoundly their working mechanism and the limitation factors. 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.
