Journal ArticleDOI
Room-temperature single-phase Li insertion/extraction in nanoscale Li(x)FePO4.
Pierre Gibot,Montse Casas-Cabanas,Lydia Laffont,Stephane Levasseur,Philippe Carlach,Stéphane Hamelet,Jean-Marie Tarascon,Christian Masquelier +7 more
TL;DR: The feasibility to drive the well-established two-phase room-temperature insertion process in LiFePO4 electrodes into a single-phase one by modifying the material's particle size and ion ordering is reported.
Journal ArticleDOI
Toward Understanding of Electrical Limitations (Electronic, Ionic) in LiMPO4 (M = Fe , Mn) Electrode Materials
Charles Delacourt,Lydia Laffont,Renaud Bouchet,C. Wurm,Jean-Bernard Leriche,Mathieu Morcrette,J. M. Tarascon,Christian Masquelier +7 more
TL;DR: In this paper, a topotactic two-phase electrochemical mechanism between LiMnPO 4 and the fully delithiated phase MnPO 4 (a = 5.909(5) A, b = 9.64(1) A), and c = 4.768(6) A).
Journal ArticleDOI
Study of the LiFePO4/FePO4 Two-Phase System by High-Resolution Electron Energy Loss Spectroscopy
Lydia Laffont,Charles Delacourt,Pierre Gibot,M. Yue Wu,Patricia J. Kooyman,and C. Masquelier,J. Marie Tarascon +6 more
TL;DR: In this paper, a detailed study of the deinsertion/insertion mechanism of the LiFePO4 insertion electrode was performed by high-resolution electron energy loss spectroscopy on thin platelet-type particles of LixFePO 4 (bPnma axis normal to the surface).
Journal ArticleDOI
Study of the insertion/deinsertion mechanism of sodium into Na0.44MnO2.
TL;DR: It is shown that HCl treatment has a detrimental effect on these electrochemical properties because of structural and textural evolutions and the insertion process within the NaxMnO2 system is fully reversible over the 0.65 composition range.
Journal ArticleDOI
Towards a Fundamental Understanding of the Improved Electrochemical Performance of Silicon–Carbon Composites†
Juliette Saint,Mathieu Morcrette,Dominique Larcher,Lydia Laffont,Shane D. Beattie,Jean-Paul Peres,David Talaga,Michel Couzi,Jean-Marie Tarascon +8 more
TL;DR: In this article, a silicon-carbon composites consisting of Si particles embedded in a dense and nonporous carbon matrix are prepared by pyrolysis of intimate mixtures of polyvinyl chloride (PVC) and Si powder at 900°C under a flow of N2.
