NOVELTY - A high-nickel ternary material preparing method involves preparing precursor solution by mixing nickel sulfate Hexahydrate, cobalt sulfate heptahydrate and manganese chloride tetrahydrate at molar ratio of 6: 2: 2, and adding water-soluble organic solvent carbon chain arranged in the secondary distilled water, followed by performing mix-calcination by adding lithium hydroxide and precursor, allowing mixture to the alumina crucible, calcinicing in muffle furnace at heating rate of 1-10 degrees C/min, 500 degrees C for 4-10 hours, to obtain product.    USE - Method for preparing high-nickel ternary material of lithium-ion battery.    ADVANTAGE - The ternary material is easy to control in appearance, simple in process and suitable for industrialized production.    DETAILED DESCRIPTION - A high-nickel ternary material preparing method involves preparing precursor solution by mixing nickel sulfate Hexahydrate, cobalt sulfate heptahydrate and manganese chloride tetrahydrate at molar ratio of 6: 2: 2, and adding water-soluble organic solvent carbon chain arranged in the secondary distilled water, an ultrasonic dispersion to obtain mixed solution A, pouring 0.1 mol/l sodium hydroxide solution into L four-necked flask, and adding complexing agents, chelating agents and additives, at (1 to 2): 1: 1: (1 to 2), to give mixed solution B under uniform stirring, with a constant flow pump at a constant speed of the mixed solution A mixed solution B added sodium hydroxide added dropwise and stirring continued after the end of completely uniform 10-60 minutes, under nitrogen, the mother liquor obtained after subjected to suction filtration, washing, filter press, secondary drying, ground and sieved, to obtain non-spherical precursor Ni(0.6)Co(0.2)Mn(0.2)OH2, followed by performing mix-calcination by adding lithium hydroxide and precursor, allowing mixture to the alumina crucible, calcinicing in muffle furnace at heating rate of 1-10 degrees C/min, 500 degrees C for 4-10 hours, at a constant temperature of 800 degrees C for 12-24 hours to obtain product.
