▎ 摘　　要

NOVELTY - Graphene conductive paste premix comprises graphene and poly(3-thiophene acrylic acid). USE - The graphene conductive paste premix is used for preparing lead-acid batteries. ADVANTAGE - The graphene conductive paste premix uses poly(3 thiophene acrylic acid) to modify the graphene, which improves the water solubility of graphene, has high viscosity and excellent stability, and improves the conductivity of the conductive paste. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: a preparation method of the graphene conductive paste premix comprising (S1) mixing the graphene, poly(3-thiophene acrylic acid) and a solvent and (S2) stirring at low pressure and performing high-pressure shearing to obtain the product; a graphene conductive paste comprising the graphene conductive paste premix, humic acid, carbon black, barium sulfate, lignin and water; and a preparation method of the graphene conductive paste comprising (a) mixing the graphene conductive paste premix with humic acid, carbon black, barium sulfate, lignin and water and (b) carrying out a homogenizing treatment and removing iron to obtain the graphene conductive paste.
