Carbon gelatinized lignin for lead storage battery and preparation method thereof

The invention discloses carbon gelatinized lignin for a lead storage battery and a preparation method of the carbon gelatinized lignin. The carbon-gelled lignin for the lead storage battery is prepared from raw materials in parts by weight, 3-5 parts of gas phase method nano silicon dioxide, 2.5-3.5 parts of graphene, 3-4.5 parts of semi-carbon lignin, 10-12 parts of deionized water, 5.1-5.6 partsof acetone, 7.5-8.8 parts of sulfuric acid, 0.4-0.7 parts of barium hydroxide, 0.18-0.23 parts of aluminum silicate, 0.25-0.35 parts of nano barium sulfate and 0.03-0.05 parts of polyacrylamide. Thecarbon gelatinized lignin for the storage battery is applied to a lead-acid storage battery, while porosity of the active substance of the polar plate is improved and the surface energy of the activesubstance is increased, technical difficulties that the battery capacity, the large-current discharge and the cycle life are influenced due to high electrolyte permeability and large electrode concentration polarization in the
