Dispersion treatment method of carbon nanotubes in oil slurry

The invention belongs to the field of new materials, and particularly relates to a dispersion treatment method of carbon nanotubes in oil slurry, which specifically comprises the steps of carbon nanotube solution preparation, pre-dispersion, oil slurry pretreatment, high-speed stirring dispersion and ultrasonic treatment. The method comprises the following steps: pre-dispersing the carbon nanotubes by adopting a solvent, pre-treating the oil slurry, stirring at a high speed within a certain temperature range, proportionally adding the pre-dispersed carbon nanotube solution into the oil slurry in batches, stirring at a high speed for a certain time, and carrying out ultrasonic treatment to finally obtain a mixed solution of the carbon nanotubes and the oil slurry, which is good in dispersion effect and good in stability. The method can be used for preparing the carbon nanotube-doped composite battery negative electrode coke. The method has the characteristics of simple process, convenience in operation and hig
