| titleOfInvention | Manufacturing method of positive electrode material for rechargeable lithium ion battery |
| abstract | Contains Ni and Co, A is a dopant, and -0.03≤a≤0.06, 0.05≤x≤0.35, 0.10≤z≤0.95, x+y+z=1 and k≤0.05 with the general formula Li 1+a ( A method for producing a powdered positive electrode material comprising single crystal monolithic particles having (Ni z (Ni ½ Mn ½ ) y Co x ) 1-k A k ) 1-a O 2 , comprising: - Ni- and Co- containing precursors and a Li-containing precursor, - subjecting the mixture to a multi-stage sintering process, whereby in the final sintering stage it contains agglomerated primary particles having a primary particle size distribution with a D50 of 2.0 to 8.0 μm. obtaining a sintered lithiated intermediate material, - subjecting the lithiated intermediate material to a wet ball milling step, whereby the agglomerated primary particles are deagglomerated and a slurry comprising the deagglomerated primary particles is obtained. - separating the deagglomerated primary particles from the slurry, and - heat treating the deagglomerated primary particles to a temperature between 300°C and at least 20°C lower than the temperature in the final sintering step of the multi-stage sintering process; , thereby obtaining single crystal monolithic particles comprising Ni and Co. |
