Abstract

L'invention concerne un procédé de préparation et l'utilisation d'un matériau d'électrode positive au phosphate de fer-lithium, comprenant les étapes suivantes : (1) le mélange à sec et le raffinage d'une source de fer, d'une source de phosphore, d'une source de lithium, d'une source de carbone et d'un additif pour obtenir un matériau mixte ; (2) le frittage du matériau mélangé pendant une première durée, puis le broyage, pour obtenir un matériau broyé ; et (3) le frittage du matériau broyé pendant une second durée, pendant laquelle une source de carbone organique gazéifiable est introduite, puis le refroidissement, pour obtenir le matériau d'électrode positive au phosphate de fer-lithium. Le procédé comprend l'utilisation d'un dispositif de mélange de matériau à haut rendement pour effectuer, en une étape, un raffinage par mélange, un frittage et un broyage des matières premières, avant la réalisation d'un frittage secondaire et d'un revêtement de carbone supplémentaire à l'aide d'une source de carbone organique gazéifiable, pour permettre à celui-ci d'avoir une meilleure couche de revêtement de carbone et une meilleure morphologie de particule. Le produit obtenu présente une meilleure performance, et comparé au même type de produits sur le marché, le produit présente des performances considérablement améliorées, une bonne stabilité de circulation, et peut satisfaire aux exigences générales d'une batterie au phosphate de fer-lithium à haute performance.
