Beschreibung
Zusammenfassung:	The present invention relates to an electrode material consisting of a lithium-rich manganese rich oxide compound doped with copper particularly useful as cathode 5 material in lithium-ion batteries of formula (I) LiaMa'MnbNixCoyCuzO2 (I), wherein: M is selected from Na, Li, K and mixtures thereof; 1.05 ≤ a+a' ≤ 1.30; 0.55 ≤ b≤ 0.70; 0.15 ≤ x ≤ 0.30; 0.025 ≤ y ≤ 0.125; and 0.05 < z ≤ 0.125. La présente invention concerne un matériau d'électrode constitué d'un composé d'oxyde riche en manganèse riche en lithium dopé avec du cuivre particulièrement utile en tant que matériau de cathode dans des batteries au lithium-ion de formule (I)LiaMa'MnbNixCoyCuzO2 (I), dans laquelle : M est choisi parmi Na, Li, K et des mélanges de ceux-ci ; 1,05 ≤ a + a'≤ 1,30 ; 0,55 ≤ b ≤ 0,70 ; 0,15 ≤ x ≤ 0,30 ; 0 025 ≤ y ≤ 0 125 ; et 0,05 < z ≤ 0,125.
