[0026]
[0027] A preparation method of lithium battery cathode material, which comprises the following steps:
[0028] Step A. Divide the positive active material into three equal parts, divide the conductive agent into three equal parts, divide the binder into four parts according to the weight ratio of 1:1:1:1.2, and divide the dispersant into 1:1:1:2 is divided into four parts, pour the first part of the binder into the mixer filled with solvent, and add the first part of the conductive agent and the first part of the first part to the mixer while stirring Positive active material, after adding the first aliquot of the conductive agent and the first aliquot of the positive active material, add the first dispersant to the blender, stir at high speed for 1 hour and then vacuum, when the vacuum in the blender reaches 0.01 When the pressure is MPa, continue pumping for 3 minutes and stir at medium speed for 1.5 hours under vacuum. After stirring, turn off the vacuum, add 0.2% abs...
