The size of the hydroxide precursor ranges from 3μm to 18μm. Solid-phase sintering PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC field process conditions are: At the heating rate of 3℃/min-5℃/min, it is heated to 450℃-550℃ for 4h-6h, and then heated to 600℃-800℃ for 10h-16h at the heating rate of 3℃/min-5℃/min. Lithium source is lithium hydroxide, lithium carbonate, lithium oxalate, lithium chloride, lithium nitrate in one or more.
The sodium source is one or more of sodium hydroxide, sodium carbonate, sodium oxalate, sodium chloride and sodium nitrate. By controlling the PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC process parameters of the precursor reaction process, pores were created inside the precursor, and the precursor with uniform distribution of internal pores was synthesized, and the residual sodium on the surface of the layered oxide cathode material was reduced by optimizing the sintering process conditions.
The controllable preparation of p2 and o3 phase cathode materials with different sodium content is realized. The particle size range of the hydroxide precursor prepared by PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC is 3μm-18μm, the specific surface area is 8m2/g-30m2/g, the vibrational density is 1.2g/cm, 3-2.5g/cm3, and the surface area is 8m2/g-30m2/g. The size of the internal pore size of the particles is 20nm-200nm.
