Abstract

La présente invention concerne du phosphate de fer-manganèse de type huréaulite et sa méthode de préparation et son utilisation. La formule chimique générale du phosphate de fer-manganèse de type huréaulite est (Mn<sub>x</sub>Fe<sub>1-x</sub>)<sub>5</sub>(PO<sub>4</sub>)<sub>2</sub>[PO<sub>3</sub>(OH)]<sub>2</sub>·4H<sub>2</sub>O, où 0,2 ≤ x < 1. La structure d'huréaulite de la présente invention est un phosphate ayant un manganèse divalent relativement stable, et peut être un précurseur idéal pour le phosphate de lithium-manganèse-fer. La méthode de préparation utilise une source de manganèse divalent soluble et une source de fer divalent soluble pour la coprécipitation, la structure d'huréaulite uniformément dopée au manganèse-fer est préparée par régulation d'un rapport manganèse-fer-phosphore, d'un pH, et d'une température de réaction dans des plages appropriées, et le manganèse et le fer peuvent être mélangés à un niveau atomique. Dans la présente invention, la teneur en élément du phosphate de fer-manganèse et la valeur théorique d'une forme cristalline de l'huréaulite sont élevées en conformité, et le rapport de teneur est stable. Le phosphate de lithium-manganèse-fer préparé par ponçage et frittage du précurseur de la présente invention, d'une source de phosphore, d'une source de lithium et d'une source de carbone présente une capacité de batterie, une performance de cycle et une densité de compactage relativement élevées.The present invention relates to hureaulite type iron-manganese phosphate and its preparation method and use. The general chemical formula of hureaulite type iron-manganese phosphate is (Mn<sub>x</sub>Fe<sub>1-x</sub>)<sub>5</sub>(PO<sub>4</sub>)<sub>2</sub>[PO<sub>3</sub>(OH)]<sub>2</sub>·4H<sub>2</sub>O, where 0.2 ≤ x < 1. The hureaulite structure of the present invention is a phosphate having relatively stable divalent manganese, and can be an ideal precursor for lithium-manganese-iron phosphate. The preparation method uses a soluble divalent manganese source and a soluble divalent iron source for coprecipitation, the uniformly doped manganese-iron hureaulite structure is prepared by regulating a manganese-iron-phosphorus ratio, a pH, and a reaction temperature within appropriate ranges, and manganese and iron can be mixed at an atomic level. In the present invention, the element content of iron-manganese phosphate and the theoretical value of a crystal form of hureaulite are high in conformity, and the content ratio is stable. The lithium-manganese-iron phosphate prepared by grinding and sintering the precursor of the present invention, a phosphorus source, a lithium source, and a carbon source has a relatively high battery capacity, cycle performance, and packing density.
