Abstract

L'invention concerne une méthode de préparation de phosphate ferrique, comprenant les étapes suivantes : mélanger un tensioactif avec une première solution de métal contenant des éléments de fer et de phosphore, ajouter un germe cristallin, laisser vieillir sous chauffage et agitation, filtrer et sécher et fritter le résidu de filtre obtenu pour obtenir le phosphate ferrique, le germe cristallin étant du phosphate ferrique dihydraté ou du phosphate ferrique d'ammonium basique. Dans la présente invention, le germe cristallin est modifié au moyen du tensioactif pour améliorer l'activité de la surface du germe cristallin, et ensuite Fe<sup>3+</sup> et PO4<sup>3-</sup> sont induits à croître de manière épitaxiale sur la surface du germe cristallin, générant ainsi des noyaux cristallins secondaires, et induisant la formation du squelette de base des particules de produit. Au moyen du procédé de vieillissement, le dépôt de noyaux cristallins sur la surface du germe cristallin rend le squelette des particules cristallines plus complet, de sorte que l'agencement de particules primaires est plus compact et ordonné, et a tendance à former des particules sphériques. La taille des particules D50 du phosphate ferrique anhydre obtenu final est de 2 à 30 µm, et les particules sont contrôlables, faciles à laver, moins humides et faciles à sécher. Les particules secondaires ont une morphologie uniforme et une densité après tassement élevée, et sont appropriées pour préparer des batteries au lithium fer phosphate compactées à haute pression.
