Abstract

Sont décrits un matériau d'électrode positive à ions lithium pré-lithié, un procédé de préparation de celui-ci et son utilisation. Le matériau d'électrode positive à ions lithium a pour formule chimique Li<sub>2</sub>O/[A<sub>(3-x)</sub>Me<sub>x</sub>]<sub>1/3</sub>-LiAO<sub>2</sub>, où A comprend M, et où M est au moins l'un des Ni, Co et Mn ; et où Me est au moins l'un des Ni, Mn, Al, Mg, Ti, Zr, Y, Mo, W, Na, Ce, Cr, Zn ou Fe ; et où 0 < x < 0,1. Le matériau est co-dopé avec plusieurs éléments, et ces éléments agissent en synergie pour inhiber le changement de phase irréversible à haute tension et améliorer la stabilité de la structure d'un substrat. La structure de phase spinelle A<sub>(3-x)</sub>Me<sub>x</sub>O<sub>4</sub> contient les éléments dopants, qui agissent ensemble pour améliorer l'activité interfaciale du matériau et introduire davantage de sites électrochimiquement actifs.
