The invention provides a lead carbon battery cathode, which comprises the following components by mass part: 85-115 of lead powder; 0.5-15 of a metal oxide; 0.1-40 of a carbon material; 9-12 of sulfuric acid; 0.2-3 of barium sulfate; 0-2.5 of sodium lignosulfonate; 0.1-3 of humic acid; 0.05-1 of short fiber, 14-16 of water, and 0.18-0.25 of barium stearate. According to the lead carbon battery cathode provided by the invention, a composite material of a heteroatom doped zero-dimension carbon material and a one-dimensional carbon nano-conductive agent is applied to a lead carbon battery cathode lead paste additive so as to form a three-dimensional network in the cathode, thereby reducing carbon material consumption, increasing the battery cathode conductivity and active substance utilization, and improving the charging acceptance ability and specific power of lead storage batteries.
