摘要: The invention provides a positive electrode material for lithium ion batteries, comprising a lithium transition metal-based oxide powder having a general formula Li 1+a ((Ni z (Ni 0.5 Mn 0.5 ) y CO x ) 1-k A k ) 1-a O 2 , wherein A is a dopant, with -0.025≤a≤0.025, 0.18≤x≤0.22, 0.42≤z≤0.52, 1.075
- the lithium transition metal-based oxide powder has a carbon content ≤1000 ppm or even ≤400 ppm;
- the lithium transition metal-based oxide powder has a sulfur content between 0.05 and 1.0 wt%;
- the powder further comprises between 0.15 and 5 wt% of a LiNaSO 4 secondary phase.-
