Journal ArticleDOI
Electrochemical storage of lithium in multiwalled carbon nanotubes
TL;DR: In this article, a tubular carbon host with graded texture and chemical composition is used for studying the electrode processes during insertion and extraction of lithium in an aprotic medium, and the specific capacity, that is, the degree of irreversible (500 −100 −g−1) and reversible (400 −100 ¼ −g −1) insertion of lithium, has been estimated from galvanostatic charge-discharge characteristics.
Journal ArticleDOI
Electrochemical insertion of lithium in catalytic multi-walled carbon nanotubes
TL;DR: In this article, the irreversible capacity for the MWNTs is relatively large, but decreasing with annealing temperature, which clearly shows that the intrinsic entanglement and the microtexture of the nanotubes must be responsible for this drawback.
Journal ArticleDOI
Bacterial degradation of large particles in the southern Indian Ocean using in vitro incubation experiments
Christos Panagiotopoulos,Richard Sempéré,Ingrid Obernosterer,L Striby,Madeleine Goutx,S. Gautier,Raymond Lafont +6 more
TL;DR: In this paper, large particles (>60 μm) were collected at 30 and 200 m water depth by in situ pumps in the southern Indian Ocean in January and February 1999, and were incubated under laboratory conditions with their own bacterial assemblages for 7-17 days in batches under oxic conditions in the dark.
Journal ArticleDOI
Effects of post-treatments on the performance of hard carbons in lithium cells
Frédéric Chevallier,S. Gautier,Jean-Paul Salvetat,Christian Clinard,Elzbieta Frackowiak,Jean-Noël Rouzaud,François Béguin +6 more
TL;DR: In this paper, the authors estimate the amount of residual lithium trapped in hard carbons when they are used for the negative electrode of lithium-ion batteries, i.e., not involved in the solid electrolyte interface (SEI) after a full deinsertion, and reduce the irreversible capacity due to the SEI formation.
