Abstract

Procédé de fabrication d'un matériau de phosphate de fer lithié enrobé de carbone, comprenant les étapes suivantes : (a) préparation d'une première suspension, d'une source de lithium et d'une première source de carbone, la première suspension étant composée d'une source de fer et d'une source de phosphore, la première source de carbone ayant une première masse égale à une valeur initiale ; (b) mélange et broyage de la première source de carbone, de la source de lithium et de la première suspension pour former une deuxième suspension ; (c) analyse de la teneur en carbone de la deuxième suspension afin d'obtenir une valeur de perte, inférieure à la valeur initiale et supérieure à zéro ; (d) ajout d'une deuxième source de carbone, de masse égale à la valeur de perte, à la deuxième suspension pour former une troisième suspension ; (e) séchage et frittage de la troisième suspension pour former le matériau de phosphate de fer lithié enrobé de carbone.
