The invention relates to an electrode material and a lead-acid battery negative electrode lead paste containing the same, in particular to a lead sulfate-graphene composite electrode material and a lead-acid battery negative electrode lead paste containing the same, solving the problems of the traditional electric vehicles and energy-storage lead-acid battery, such as poor high rate discharging cycling performance of the negative electrode and short service life. In the lead sulfate-graphene composite electrode material, lead sulfate is loaded on graphene, wherein the weight ratio of lead sulfate to graphene is (0.1-10):1. The mass of the composite electrode material in the lead-acid battery negative electrode lead paste is 0.1% to 10% of the mass of lead powder. The composite electrode material has reversible oxidation-reduction performance and capacitance performance, and can reduce the hydrogen-evolving potential of graphene, thereby providing more lead sulfate growth points for the lead-acid negative electrode, suppressing the sulfation of the negative electrode of a lead-acid battery in the high rate charging-discharging process, and prolonging the service life of the lead-acid super battery. With the first pulse discharging cycling frequency of more than 6,000 times, the negative electrode lead paste is suitable for the negative electrode material of electric vehicles and energy-storage lead-acid batteries.
