Abstract
La présente invention relève du domaine de la récupération de matériaux de batteries. La présente invention concerne un procédé de préparation de phosphate de fer de type fer d'isophosphorite et une application associée. Le procédé comprend les étapes suivantes : mélange de phosphate de fer de lithium avec un solvant et ajout d'une solution acide pour ajuster le ph pour qu'il soit acide, de manière à obtenir une solution acide de phosphate de fer de lithium ; ajout d'un additif de métal de transition dans la solution acide de phosphate de fer de lithium ; et réalisation d'un renforcement de microenvironnement, d'une réaction de lixiviation et d'un filtrage pour obtenir du phosphate de fer de type fer d'isophosphorite et une solution riche en lithium. Selon la présente invention, du phosphate de fer de lithium et de l'eau sont mélangés et un acide est ajouté pour maintenir le ph entre 2 et 6, puis un additif de métal de transition nickel-cobalt-manganèse est ajouté au moyen d'un procédé de renforcement de microenvironnement pour réaliser une réaction de catalyse et de renforcement en surface, de manière à favoriser la génération de radicaux hydroxyle et à améliorer considérablement un taux d'oxydation du fer divalent, permettant ainsi de mettre en œuvre une lixiviation sélective du lithium dans un état oxygène/air, le taux de lixiviation du lithium dans une solution de lixiviation atteignant 90,5 à 99,9 %, et les teneurs en fer et en phosphore dans la solution de lixiviation étant toutes deux inférieures à 0,1 ppm.
