NOVELTY - Preparing layered structure graphene-titanate lead-acid battery electrode active material additive involves dissolving titanium aluminum carbide (Ti3AlC2) powder in a mixed solution of lithium fluoride (LiF) and hydrogen chloride (HCl), and heating the reaction to prepare a Ti3C2Tx macoene suspension. The graphene oxide aqueous solution is added to the Ti3C2Tx macoene suspension. The Ti3C2Tx macoene/reduced graphene oxide composite material is prepared by the thermal reduction method. The mixed aqueous solution obtained by using sodium hydroxide, lead hydroxide and hydrogen peroxide are added to the composite slurry, and after hydrothermal treatment and drying, the reduced graphene oxide/sodium titanate/lead titanate layered two-dimensional material composite material with a sandwich structure is obtained. USE - Method for preparing layered structure graphene-titanate lead-acid battery electrode active material additive. ADVANTAGE - The prepared layered two-dimensional material composite material has the advantages of large layer spacing, excellent electrical conductivity, high reactivity, high chemical stability, etc., and can assist electrode materials to provide lead sources, and has a synergistic effect with high specific capacitance graphene to increase the capacity, and more importantly, it can significantly improve the electrochemical performance and cycle stability of lead-acid batteries, and extend the service life.
