Abstract

La présente invention se rapporte au domaine technique des matériaux de batterie. La divulgation concerne un phosphate de fer (III) dopé, son procédé de préparation et son utilisation. La formule chimique du phosphate de fer (III) dopé est (Mn<sub>x</sub>Fe<sub>1-x</sub>)@FePO<sub>4</sub>•2H<sub>2</sub>O, où 0 < x < 1. Selon la présente invention, du phosphate de ferromanganèse est utilisé en tant qu'agent structurant pour préparer le phosphate de fer (III) dopé. Le phosphate de fer (III) dopé présente une morphologie régulière et une bonne fluidité, facilite le lavage et le transport, et peut améliorer les performances électrochimiques du LiFePO<sub>4</sub>/C préparé par la suite. Lorsque la quantité de dopage de Mn est de 11000 ppm, la capacité de décharge spécifique de LiFePO<sub>4</sub>/C à température ambiante à 0,1 C peut atteindre 165 mAh/g ; le taux de rétention de la capacité de décharge de 1000 cycles à 45 °C à 1 C peut atteindre 97,4 % ; et à une basse température de -15 °C, la capacité de décharge spécifique à 0,1 C est encore 134 mAh/g.
