The application provides a lithium negative electrode slurry and a homogenizing process thereof. The negative electrode slurry comprises graphite, a conductive agent, a binder, a thickening agent and a solvent. The conductive agent comprises at least one of carbon nanotubes, conductive carbon black and graphene. The thickening agent comprises sodium carboxymethyl cellulose. The binder comprises PAA or a water-based binder copolymerized with PAA, and butadiene styrene rubber. The solvent is deionized water. The total solid content of the negative electrode slurry is 46-50%, and the initial viscosity is 2500-4000 mPa.S. The negative electrode slurry is prepared by combining dry and wet methods. The application has the advantages that carbon nanotubes, carbon black and graphene can be effectively used as the negative electrode composite conductive agent in the water-based negative electrode slurry, the negative electrode slurry has good dispersion effect, good stability, good coating performance and is not prone to delamination, and the negative electrode plate can be effectively improved in resistivity, reduced in impedance, improved in energy density of the battery cell and increased in liquid retention.
