Abstract

La présente invention concerne un matériau d'électrode positive, son procédé de préparation et son utilisation. Le matériau d'électrode positive selon la présente invention comprend : un matériau d'électrode positive en couches ayant la formule chimique Li<sub>x</sub>MO<sub>2</sub> et une substance de revêtement, x allant de 0,95 à 1,1, et M étant un métal de transition comprenant Mn. La substance de revêtement est disposée sur une surface du matériau d'électrode positive en couches, et vient partiellement doper une couche de surface du matériau d'électrode positive en couches. La substance de revêtement comprend du manganèse tétravalent, des ions lithium et des ions phosphate. Le matériau d'électrode positive selon la présente invention peut efficacement inhiber la dissolution de manganèse à partir d'un matériau d'électrode positive contenant du manganèse, ce qui permet d'améliorer les performances de cycle. La présente invention concerne également un procédé de préparation du matériau d'électrode positive, et une utilisation de celui-ci.
