▎ 摘  要

NOVELTY - Cobalt-free positive electrode slurry includes a cobalt-free positive electrode material, a conductive agent, a binder, a conductive polymer, and a solvent. USE - Cobalt-free positive electrode slurry for use in an anode sheet of a lithium ion battery (all claimed). ADVANTAGE - The cobalt-free anode slurry improves the conductivity of the cobalt-free positive electrode sheet, reduces the inner resistance of the electric core, has higher ion conductivity, improves battery power performance, improves the surface density of the anode pole piece, so as to improve the energy density of the battery, reduces the dissolution phenomenon of metal residue, reduces the self-discharge phenomenon of the battery, and improves the safety factor of the battery. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the cobalt-free positive electrode slurry, which involves: (A) mixing conductive polymer with the first solvent to obtain a first mixed glue solution, and mixing the binder and the second solvent to obtain a second mixed glue solution; and (B) mixing the cobalt-free positive electrode material, the conductive agent, the first mixed glue solution and the second mixed glue solution to obtain the cobalt-free positive electrode slurry.
