Abstract

The present application discloses a lead-carbon battery negative electrode lead paste, a preparation method and a battery plate, a preparation method and an application, comprising the following raw materials in parts by weight: lead powder, 100 parts; graphene-based polymer, 5-10 parts; barium sulfate, 0.5-1.0 parts; humic acid, 0.05-0.5 parts; short fibers, 0.05-0.3 parts; conductive carbon black, 0.01-0.5 parts; water, 0.1-5 parts; wherein the graphene-based polymer is prepared by doping at least one of polypyrrole and polyaniline with lignin sulfonate, using graphene as a skeleton. The present invention provides a graphene-based polymer slurry lead-carbon negative electrode lead paste and a preparation method thereof. It is applied to traditional lead-acid batteries, and the introduction of graphene-based polymer composite materials prolongs the cycle life of the battery at high rate partial charge.
