Abstract
L'invention concerne un procédé de purification de graphite et de reconstruction de réseau dans une batterie d'alimentation, comprenant les étapes suivantes consistant : à soumettre successivement une batterie d'alimentation usagée à une décharge, un broyage grossier, une pyrolyse, un broyage fin et un tri pour obtenir une poudre de matériau d'électrode ; à mélanger la poudre de matériau d'électrode et un agent d'extraction de métaux, à laisser reposer, à laver avec un agent de purification A, et à filtrer pour obtenir un résidu de filtration A ; à mélanger le résidu de filtration A et de l'agent d'extraction de métaux, à laisser reposer, à laver avec un agent de purification B, et à filtrer pour obtenir du graphite brut ; à réaliser un traitement d'élimination organique, un refroidissement, un broyage à boulets et un remplacement de ventilation sur le graphite brut pour obtenir du graphite principalement purifié ; et à introduire un gaz rare dans le graphite principalement purifié pour réparer les réseaux de graphite. Selon le procédé, des constituants organiques dans le graphite sont éliminés d'une manière similaire à l'évaporation sous vide, des impuretés organiques sont évaporées ou sublimées sous forme de particules gazeuses dans des conditions de vide à haute température, les particules gazeuses sont complètement séparées du graphite sous une pression négative, et des matières organiques peuvent être éliminées, de façon à obtenir du graphite de grande pureté.
