Abstract

La présente invention se rapporte au domaine technique des matériaux de batterie. L'invention concerne un matériau d'électrode négative composite silicium-carbone, son procédé de préparation et son application. Le procédé de préparation comprend les étapes suivantes : dissoudre la poudre d'électrode négative de graphite dans une solution acide, réaliser une séparation solide-liquide, obtenir un précipité, laver et sécher celui-ci, ajouter un agent réducteur, et réaliser un traitement thermique pour obtenir un matériau de graphite purifié ; et ajouter la poudre de silicium modifiée au matériau de graphite et mélanger les deux, puis ajouter le mélange à une solution de diméthyformamide contenant du polyimide, agiter, distiller et réaliser un traitement de carbonisation pour obtenir un matériau d'électrode négative composite silicium-carbone. Selon la présente invention, la poudre d'électrode négative en graphite récupérée est purifiée au moyen d'une lixiviation acide, et est en outre purifiée par ajout d'un agent réducteur dans une atmosphère de chlore pour un traitement thermique, ce qui permet d'améliorer la pureté de la poudre de graphite récupérée.
