Abstract

La présente demande se rapporte au domaine technique des batteries au lithium-ion. Sont divulgués un lithium fer phosphate dopé encapsulé dans un ligand, son procédé de préparation et son utilisation. Le lithium fer phosphate dopé encapsulé dans un ligand répond à la formule générale lifepo4@mn-t-c/n ; et t représente au moins un élément parmi le zinc, le nickel, le cuivre, le fer, le cobalt, le zirconium, l'aluminium, le gallium et le chrome. Le lithium fer phosphate dopé encapsulé dans un ligand est de type dopant par dopage comportant un microconducteur à sphères de carbone supporté par composite. Le microconducteur à sphères de carbone supporté par composite présente une taille de particule située dans la plage allant de 80 à 150 nm, et peut ainsi résister à une contrainte supérieure et réduire la probabilité de fissuration. L'intégrité structurale du lithium fer phosphate sphérique dopé comportant le microconducteur à sphères de carbone supporté par composite est plus facile à commander.
