The invention provides a battery cathode material. The battery cathode material comprises sulfur particles, a conductive additive and graphene, wherein the sulfur particles are loaded on the surface of the conductive additive; the conductive additive and the sulfur particles are wrapped into the graphene; and the conductive additive comprises the following constituents based on weight: 1-10 parts of Pb3O4 and 25-50 parts of Beta-PbO2. By the battery cathode material, the content of lead dioxide is increased, the polar plate formation difficulty is reduced, and the capacity of a polar plate is improved; with the addition of the Beta-PbO2, the capacity of a battery can be improved, and meanwhile, the charging and discharging voltage of the battery is increased slightly; and by adjusting the proportion of the Pb3O4 and Beta-PbO2, the strength of the polar plate, the charging and discharging voltage at an early stage, the charging and discharging voltage at a post stage, the cyclic post-stage capacity and the like are improved to an ideal level.
