Journal ArticleDOI
NMR studies of cathode materials for lithium-ion rechargeable batteries.
Clare P. Grey,Nicolas Dupré +1 more
TL;DR: The first commercial Li-ion rechargeable battery contains the layered materials LiCoO2 and graphite as the cathode and anode (or negative electrode), respectively, which is the current standard in many applications including cell phones and laptops.
Journal ArticleDOI
The failure mechanism of nano-sized Si-based negative electrodes for lithium ion batteries
Y. Oumellal,Nathalie Delpuech,Driss Mazouzi,Nicolas Dupré,Joël Gaubicher,Philippe Moreau,Patrick Soudan,Bernard Lestriez,Dominique Guyomard +8 more
TL;DR: In this paper, Li et al. demonstrated that the main cause of capacity fade of Si-based negative electrodes is the liquid electrolyte degradation in the case of nano Si-particles formulated with the carboxymethyl cellulose (CMC) binder.
Journal ArticleDOI
High-resolution X-ray diffraction, DIFFaX, NMR and first principles study of disorder in the Li2MnO3-Li[Ni1/2Mn1/2]O2 solid solution
Julien Breger,Meng Jiang,Nicolas Dupré,Ying Shirley Meng,Ying Shirley Meng,Yang Shao-Horn,Gerbrand Ceder,Clare P. Grey +7 more
TL;DR: In this paper, the authors show that even well-ordered cation layers may show only weak or no superstructure reflections, if there is no or little ordering in the c-direction.
Journal ArticleDOI
Short- and long-range order in the positive electrode material, Li(NiMn)0.5O2: a joint X-ray and neutron diffraction, pair distribution function analysis and NMR study.
Julien Breger,Nicolas Dupré,Peter J. Chupas,Peter L. Lee,Thomas E. Proffen,John B. Parise,Clare P. Grey +6 more
TL;DR: Both NMR and RMC results were consistent with a nonrandom distribution of Ni, Mn, and Li cations in the transition metal layers; both the Ni and Li atoms are, on average, close to more Mn ions than predicted based on a random distribution of these ions in the Transition metal layers.
Journal ArticleDOI
Multiprobe Study of the Solid Electrolyte Interphase on Silicon-Based Electrodes in Full-Cell Configuration
Nicolas Dupré,Philippe Moreau,E. de Vito,Lucille Quazuguel,Maxime Boniface,Arnaud Bordes,C. Rudisch,Pascale Bayle-Guillemaud,Dominique Guyomard +8 more
TL;DR: In this article, a combination of 7Li, 19F MAS NMR, XPS, TOF-SIMS, and STEM-EELS was used to characterize the solid electrolyte interphase (SEI) formation on the surface of silicon.
