Abstract

L'invention concerne un graphite expansé et sa méthode de préparation. La méthode de préparation comprend les étapes suivantes consistant à : (1) dans une atmosphère protectrice, mélanger une poudre de graphite avec un peroxyde de métal et/ou un superoxyde de métal alcalin, et les laisser reposer pour obtenir un matériau composite mixte de peroxyde de métal-graphite et/ou de superoxyde de métal alcalin-graphite ; (2) mettre le matériau composite préparé à l'étape (1) dans un milieu liquide, qui peut réagir avec le peroxyde de métal et/ou le superoxyde de métal alcalin, pour une réaction pour obtenir du graphite intercalé ; et (3) chauffer le graphite intercalé préparé à l'étape (2) pour préparer le graphite expansé. La méthode de préparation peut éviter efficacement la génération d'impuretés nocives telles que le soufre et les sulfures pendant le processus de préparation du graphite expansé, ce qui permet de réduire la pollution environnementale.
