摘要：
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(Ni1/2Mn1/2)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.
