Journal ArticleDOI
Lithium rhenium(VII) oxide as a novel material for graphite pre-lithiation in high performance lithium-ion capacitors
Paweł Jeżowski,Krzysztof Fic,Olivier Crosnier,Olivier Crosnier,Thierry Brousse,Thierry Brousse,François Béguin +6 more
TL;DR: In this article, Li5ReO6 was used as a sacrificial material in the positive activated carbon electrode of a lithium-ion capacitor to be used for pre-lithiating the graphite negative electrode.
Journal ArticleDOI
The reversible intercalation of tetrahydrofuran in some graphite-alkali metal lamellar compounds
TL;DR: In this article, the second and higher stage graphite derivatives of three alkali metals reversibly react with polar molecules such as tetrahydrofuran (THF), and the compounds formed are MC24Xp wher M is K, Rb or Cs and X is the organic molecule.
Journal ArticleDOI
Pseudo-capacitance of nanoporous carbons in pyrrolidinium-based protic ionic liquids
TL;DR: Protic ionic liquids (PILs) were used as novel electrolyte for carbon-based supercapacitors in this article, where the cyclic voltammograms in three-electrode cells showed reversible redox humps, revealing pseudo-faradaic charge transfer.
Journal ArticleDOI
The first in situ 7Li NMR study of the reversible lithium insertion mechanism in disorganised carbons
TL;DR: In this paper, a disordered carbon designed to be used as negative electrode in a secondary lithium battery was studied, and it was shown that it exhibits better qualities than graphite's for secondary battery applications.
Journal ArticleDOI
Catalytically grown carbon nanotubes of small diameter have a high Young's modulus.

TL;DR: The results indicate that the observed difference in the Young's modulus for the catalytically grown CNTs with high and low numbers of walls is probably related to the growth mechanism of CNT.
