Abstract

La présente invention concerne un procédé de recyclage de batteries au lithium-fer-phosphate usagées, qui se rapporte au domaine technique du recyclage de batteries. Dans le procédé de recyclage de batteries au lithium-fer-phosphate usagées de la présente invention, un matériau d'électrode positive d'une batterie au lithium-fer-phosphate usagée est utilisé comme corps principal, et est soumis à une supplémentation en lithium et à une réparation à l'aide d'une source de lithium, d'une source de fer et d'une source de phosphore, et, en outre, une nouvelle couche de revêtement à base de lithium-fer-phosphate contenant une structure réticulée de couche de carbone est reconstruite sur sa surface, de telle sorte que la régénération du lithium-fer-phosphate est réalisée. La couche de revêtement construite comprend un matériau de graphite dans une plaque d'électrode négative à base de lithium-fer-phosphate usagée et est utilisée conjointement avec de la gélatine et du PEG comme précurseurs pour préparer un matériau de graphite modifié, qui a une excellente structure réticulée poreuse, ce qui fait que le matériau régénéré finalement préparé a un degré de dispersion élevé, une morphologie uniforme et de bonnes performances électrochimiques. Le procédé présente un taux d'utilisation élevé des matières premières des batteries usagées, et est très économique et rentable. La présente invention concerne en outre un matériau d'électrode positive à base de lithium-fer-phosphate/C régénéré préparé à l'aide du procédé de recyclage.
