Abstract

La présente invention se rapporte au domaine technique des batteries secondaires. Est divulgué un procédé de réparation d'un matériau de silicium-carbone usagé. Le procédé de réparation d'un matériau de silicium-carbone usagé comprend les étapes suivantes : (1) le prétraitement d'un matériau de silicium-carbone usagé pour obtenir un mélange pulvérulent ; (2) le mélange du mélange pulvérulent obtenu à l'étape (1) avec un composé de structure organométallique, et la réalisation d'un lavage et d'un séchage pour obtenir une poudre noire ; (3) le mélange de la poudre noire obtenue à l'étape (2) avec du graphite, la calcination de ceux-ci sous une atmosphère d'acétylène, la réalisation d'un dépôt en phase vapeur, et la réalisation d'un refroidissement, d'un lavage et d'un séchage pour obtenir un matériau de silicium-carbone. La présente invention répare un matériau d'électrode négative de silicium-carbone usagé utilisé, et comble complètement des défauts tels que des cavités et des espaces dans le matériau avec du carbone de dimensions différentes de façon à obtenir un matériau de silicium-carbone réparé ayant une stabilité structurale élevée, ce qui permet de surmonter le problème d'endommagement structural provoqué par l'expansion dimensionnelle d'un matériau de silicium pendant des processus de charge et de décharge.
