Graphite is a host material for lithium intercalation and can be used as an active anode material in rechargeable lithium cells. The battery performances and cycling depends on the type and morphology of graphite. The advantage of natural graphite is

International audience; The intercalation of certain metal chlorides into carbon fibers presents some problems, which depend on both their structure (three-dimensional ordering in particular) and the intercalation techniques. In this work, the interc

To use carbon fibers as additive in a chemical heat pump, based on a solid–gas reaction, three mixtures of carbon fibers with the reagent compounds are proposed: simple mixture, impregnation of the carbon fibers with reagent compounds and intercala

International audience; Synthesis and structural characterization of EuxC60 (x near 3 and 6) are reported. The low metal concentration phase is a vacancy ordered f.c.c.-derived phase and may be presented as a regular M3C60 phase, in which defects ari

The effect of different factors on useful properties of pitch-based graphite fibres intercalated with metal chlorides is investigated. Fibrous intercalation compounds were prepared with acceptor intercalants such as MnCl2 and CuCl2. The lowest resist

International audience; C60 doped with 4f elements yields FCC and BCC-derived structures. The phases show paramagnetic or diamagnetic behaviours, consistent most of the time with the classical picture of charge transfer between intercalant species an

We report in this paper some results on the reactivity of different carbon materials, and in particular a set of pitch-coke samples heat treated between 800 and 2400 °C, with sodium. An experimental cell has been designed, which allows carbon to rea
