Lead negative plate for graphene lead-carbon battery and preparation method thereof

The invention relates to a lead negative plate for a graphene lead-carbon battery and a preparation method thereof. The negative plate comprises a negative plate grid and a lead paste. The raw materials of the lead paste are composed of the following components: lead powder, a functionalized graphene dispersion solution, a hydrogen inhibitor, carbon black, humic acid, short fibers, barium sulfateand sodium lignosulfonate; a graphene pretreatment layer is prepared on the surface of the negative plate grid. The preparation method includes the following steps: S1, preparation of the functionalized graphene dispersion solution; S2, preparation of the lead paste; S3, preparation of a lead paste sticky material; and S4, preparation of the graphene-lead negative plate. The lead negative plate has the advantages of high charging acceptance capability, high specific power, good dispersion of graphene lead powder, small hydrogen evolution amount and long cycle life. 本发明涉及种石墨烯铅碳电池的铅负极板及其制备方法，所述负极板包括负极板栅和铅膏，所述铅膏的原料由如下组分组
