Title (EN) HIGH NICKEL CATHODE MATERIAL HAVING LOW SOLUBLE BASE CONTENT
(FR) MATÉRIAU DE CATHODE À FORTE TENEUR EN NICKEL AYANT UNE FAIBLE TENEUR EN BASE SOLUBLE
Abstract: front page image
(EN)The invention relates to cathode materials for Li-ion batteries in the quaternary phase diagram Li[Li1/3Mn2/3]O2 –LiMn1/2Ni1/2O2–LiNiO2–LiCoO2, and having a high nickel content. Also a method to manufacture these materials is disclosed. The cathode material has a general formula Lia((Niz(Ni½Mn½)yCox)1-kAk)2-aO2, wherein x+y+z=1, 0.1≤x≤0.4, 0.36≤ z ≤0.50, A is a dopant, 0≤k≤0.1, and 0,95≤a≤1.05, and having a soluble base content (SBC) within 10% of the equilibrium soluble base content.
(FR)L'invention concerne des matériaux de cathode pour batteries Li-ion dans le diagramme de phase quaternaire Li[Li1/3Mn2/3]O2 -LiMn1/2Ni1/2O2-LiNiO2-LiCoO2, et ayant une forte teneur en nickel. Elle concerne aussi un procédé de fabrication de ces matériaux. Le matériau de cathode a une formule générale Lia((Niz(Ni½Mn½)yCox)1-kAk)2-aO2, où x+y+z=1, 0,1≤x≤0,4, 0,36≤ z ≤0,50, A est un dopant, 0≤k≤0,1, et 0,95≤a≤1,05, et ayant une teneur en base soluble (SBC) dans les 10 % de la teneur en base soluble à l'équilibre.
