  "textContent": "A bimodal lithium transition metal oxide based powder mixture comprises a first and a second lithium transition metal oxide based powder. The first powder comprises particles of a material A comprising the elements Li, a transition metal based composition M and oxygen. The first powder has a particle size distribution characterized by a (D90−D10)/D50≤1.5. The second powder comprises a material B having single crystal particles, said particles having a general formula LiN′O, wherein −0.03≤b≤0.10, and N′=NiM″CoE, wherein 0.30≤x≤0.92, 0.05≤y≤0.40, 0.05≤z≤0.40 and 0≤d≤0.10, wherein M″ is one or both of Mn or Al, and E is a dopant different from M″. The first powder has an average particle size D50 between 10 and 40 μm. The second powder has a D50 between 2 and 4.5 μm. The weight ratio of the second powder in the mixture is between 15 and 60 wt %.",
