Nanosilicon Electrodes for Lithium-Ion Batteries: Interfacial Mechanisms Studied by Hard and Soft X-ray Photoelectron Spectroscopy
Bertrand Philippe,Bertrand Philippe,Rémi Dedryvère,Joachim Allouche,Fredrik Lindgren,Mihaela Gorgoi,Håkan Rensmo,Danielle Gonbeau,Kristina Edström +8 more
TL;DR: In this paper, the authors proposed silicon as an ideal candidate for the next generation of negative electrodes for Li-ion batteries, based on its very high rechargeable capacity and its ability to resist high power dissipation.
Journal ArticleDOI
Towards high energy density sodium ion batteries through electrolyte optimization
Alexandre Ponrouch,Rémi Dedryvère,Rémi Dedryvère,Damien Monti,Damien Monti,Atıf Emre Demet,Jean Marcel Ateba,Jean Marcel Ateba,Laurence Croguennec,Christian Masquelier,Christian Masquelier,Patrik Johansson,M. Rosa Palacín +12 more
TL;DR: In this article, a comprehensive study is reported entailed optimization of sodium ion electrolyte formulation and compatibility studies with positive and negative electrode materials, and EC0.45:PC0.1 was found to be the optimum composition resulting in good rate capability and high capacity upon sustained cycling for hard carbon electrodes.
Journal ArticleDOI
Fundamental interplay between anionic/cationic redox governing the kinetics and thermodynamics of lithium-rich cathodes
Gaurav Assat,Dominique Foix,Charles Delacourt,Charles Delacourt,Antonella Iadecola,Rémi Dedryvère,Jean-Marie Tarascon,Jean-Marie Tarascon,Jean-Marie Tarascon +8 more
TL;DR: Oxygen redox reactivity in the archetypical lithium- and manganese-rich layered cathodes is proved through bulk-sensitive synchrotron-based spectroscopies, and the authors reveal its crucial role in practically important properties.
Journal ArticleDOI
Interface Stability of Argyrodite Li6PS5Cl toward LiCoO2, LiNi1/3Co1/3Mn1/3O2, and LiMn2O4 in Bulk All-Solid-State Batteries
Jérémie Auvergniot,Jérémie Auvergniot,Alice Cassel,Jean-Bernard Ledeuil,Virginie Viallet,Virginie Viallet,Vincent Seznec,Vincent Seznec,Rémi Dedryvère,Rémi Dedryvère +9 more
TL;DR: In this article, the interface stability of argyrodite Li6PS5Cl was investigated for all-solid-state Li-ion half-cells and the interface mechanisms were characterized by Auger electron spectroscopy and X-ray photoelectron spectrographs.
Journal ArticleDOI
The Effect of Vinylene Carbonate Additive on Surface Film Formation on Both Electrodes in Li-Ion Batteries
L. El Ouatani,Rémi Dedryvère,C. Siret,Philippe Biensan,Stéphanie Reynaud,Pierre Iratçabal,Danielle Gonbeau +6 more
TL;DR: In this article, the effect of vinylene carbonate (VC) as electrolyte additive on the formation mechanisms of passivation films covering both electrodes in lithium-ion batteries was investigated by X-ray photoelectron spectroscopy (XPS).
