Abstract

La présente invention concerne un précurseur de phosphate de fer modifié, un phosphate de fer-lithium modifié, et des procédés de préparation associés. Le précurseur de phosphate de fer modifié est préparé par dissolution d'un sel ferrique soluble dans une suspension de diséléniure de niobium, puis par réaction avec une source d'acide phosphorique. Le précurseur de phosphate de fer modifié peut adsorber efficacement une source de lithium, ce qui permet d'améliorer significativement la conductivité du phosphate de fer-lithium.
