Journal ArticleDOI
Lithium-ion batteries - current state of the art and anticipated developments
Michel Armand,Peter Axmann,Dominic Bresser,Mark Copley,Kristina Edström,Kristina Edström,Christian Ekberg,Dominique Guyomard,Bernard Lestriez,Petr Novák,Martina Petranikova,Willy Porcher,Sigita Trabesinger,Margret Wohlfahrt-Mehrens,Heng Zhang +14 more
TL;DR: In this article, a comprehensive review of important findings and developments in this field that have enabled their tremendous success with an overview of very recent trends concerning the active materials for the negative and positive electrode as well as the electrolyte is presented.
Journal ArticleDOI
Failure mechanisms of nano-silicon anodes upon cycling: an electrode porosity evolution model
Etienne Radvanyi,Willy Porcher,Eric De Vito,Alexandre Montani,Sylvain Franger,Séverine Jouanneau Si Larbi +5 more
TL;DR: For the first time, a real dynamic of the pore size distribution is shown: the first cycles lead to the formation of a micrometric porosity which is not present initially, and from the 50th cycle, Li(+) ion diffusion is dramatically hindered leading to a strongly heterogeneous lithiation of the electrode and a rapid capacity fading.
Journal ArticleDOI
An XPS/AES comparative study of the surface behaviour of nano-silicon anodes for Li-ion batteries
TL;DR: In this paper, the surface of composite electrodes made of nano-silicon is studied by using two surface characterization techniques: X-ray Photoelectron Spectroscopy (XPS) and Auger Electron Spectrograph (AES).
Journal ArticleDOI
One-step synthesis of Si@C nanoparticles by laser pyrolysis: high-capacity anode material for lithium-ion batteries.
Julien Sourice,Axelle Quinsac,Yann Leconte,Olivier Sublemontier,Willy Porcher,Cédric Haon,Arnaud Bordes,Eric De Vito,Adrien Boulineau,Séverine Jouanneau Si Larbi,Nathalie Herlin-Boime,Cécile Reynaud +11 more
TL;DR: Carbon-covered silicon nanoparticles (Si@C) were synthesized for the first time by a one-step continuous process in a novel two stages laser pyrolysis reactor, allowing the use of such material as promising anode material in lithium-ion batteries (LIB).
