Abstract

L'invention concerne une méthode de préparation et une utilisation de lithium fer phosphate. La méthode de préparation comprend : l'ajout d'une solution mixte de sel ferreux et de dihydrogénophosphate d'ammonium, d'une solution d'acide citrique et d'un régulateur de pH en écoulement simultané dans un premier réacteur pour réaction, l'extraction du matériau dans le premier réacteur dans un second réacteur, et l'ajout d'une solution de sel de cuivre et d'une solution d'hydroxyde de sodium dans le second réacteur pour réaction, le matériau dans le second réacteur refluant dans le premier réacteur ; et le mélange du matériau solide obtenu par la réaction avec une source de lithium, et le placement du mélange dans un flux de gaz ammoniac pour la calcination pour obtenir du lithium fer phosphate. Selon la méthode, un précurseur de lithium fer phosphate d'une structure sphérique peut être préparé, de telle sorte que la performance électrochimique du matériau de lithium fer phosphate préparé par la suite est améliorée, et le matériau de lithium fer phosphate a une conductivité électrique relativement élevée.
