<p>The invention concerns carbon fibres with average inter-reticular distance (d002) at least equal to 0.36 nm, preferably 0.38 nm, having a crystallite size such that the average height (Lc) ranges between 0.7 nm and 3 nm and the average lateral dimension (La) ranges between 2 nm and 6 nm, and having a total porosity ranging between 10 % and 30 %. The electrode is preferably a carbon tissue with rayon precursor and constitutes a secondary battery anode (10) with a cathode (20) which comprises lithium, for inserting and removing lithium ions, and an electrolyte (30).</p> |
