Abstract
The invention discloses a preparation of a lithium ion battery positive electrode slurry. Deionized water is used as a dispersion medium, so that the dispersity of aqueous positive electrode slurry is improved, environmental pollution caused by use of an organic solvent is avoided, and the preparation method is more environment-friendly and safer; in the components of the aqueous positive electrode slurry, the contents of the conductive agent and the aqueous binder are optimized, and meanwhile, the high-performance graphene composite conductive slurry is also used as the conductive agent, so that the ohmic internal resistance and polarization internal resistance of the battery can be reduced, and the high-power starting performance of the lithium battery is improved.
