Abstract

La présente invention propose un procédé destiné à purifier des nanotubes de carbone bruts pour atteindre un taux d'impuretés métalliques compris entre 5 ppm et 200 ppm. Le procédé comprend une augmentation de la masse volumique apparente des nanotubes de carbone bruts par compactage pour produire des nanotubes de carbone compactés. Le procédé comprend également un frittage des nanotubes de carbone compactés par soumission à un traitement thermique sous une atmosphère gazeuse afin d'enlever au moins une partie des impuretés métalliques contenues dans les nanotubes de carbone bruts, en produisant de ce fait des nanotubes de carbone purifiés. Ces nanotubes de carbone purifiés sont directement utilisables comme des conducteurs électroniques servant comme additifs de base à un matériau d'électrode sans avoir besoin une quelconque étape ultérieure de purification. Le matériau d'électrode peut alors servir à fabriquer une électrode destinée à une batterie lithium-ion.
