Abstract：Aiming at the natural hydrophobicity and poor dispersion in water of graphite particles, taking carboxymethylcellulose sodium as a dispersing agent, the graphite aqueous slurry was prepared under the same process conditions. The effect of the carboxymethylcellulose sodium dosage and dispersion time on dispersion of flake graphite particles was studied. The results show that the best mass fraction of carboxymethylcellulose sodium is 1%. The best dispersion time is 20 min.
