Abstract

Un mélange comprenant :- de plus de 50 à 99 % en masse d’un phosphate lithié de manganèse et de fer - de 1 à moins de 50 % en masse d’au moins un oxyde lithié de nickel, de manganèse et de cobalt ou d’au moins un oxyde lithié de nickel, de cobalt et d’aluminium, ou d’un mélange de ces deux oxydes, ces deux oxydes lithiés étant riches en nickel. Ce mélange peut être utilisé comme matière active de la cathode d’un élément électrochimique lithium-ion. Le profil de charge de l’élément présente un plateau indicateur de la fin de la charge.
