▎ 摘　　要

NOVELTY - A lead carbon energy storage battery comprises a lead carbon negative plate grid, which contains 1-5%, preferably 2.5% graphite or 0.1-1% graphene, and 1-5%, preferably 2.5% Cabot 7 carbon black, and is prepared by melting and stirring above-mentioned components at 500-1100 degrees C, covering with sodium chloride for cooling and casting, a lead carbon cathode containing 0.1-0.5%, preferably 0.25% graphite, 0.1-1%, preferably 0.5% graphene or carbon nanotubes, 0.2-2%, preferably 1.1% carbon black, 0.05-0.5%, preferably 0.25% anisaldehyde and 0.1-0.5%, preferably 0.25% zinc oxide or tin oxide powder, 0.01-0.1%, preferably 0.05% indium dioxide, 2-10%, preferably 6% fumed silica powder, a PVC separator with a maximum pore diameter of 18-30 microns, preferably 24 microns and a porosity of 75-90%, preferably 85%, and an electrolyte formed by mixing organic and inorganic glues with a thickening agent through collision. The pore space of the separator is filled with 2-5%, preferably 3.5% gas phase. USE - Lead carbon energy storage battery. ADVANTAGE - The lead carbon energy storage battery: solves the problem of water loss caused by excessive carbon content in the cathode; and solves the problem of insufficient sulfation of the cathode by adding cathode carbon and the mismatch between the negative plate grid and the lead carbon formulation lead paste to improve the battery life and energy storage upper limit.
