▎ 摘　　要

NOVELTY - Preparing reduced graphene oxide loaded lead oxide composite material comprises (i) mixing graphene oxide dispersion liquid with aniline, lead acetate solution, adding in reactor and hydrothermally reacting, where the mass ratio of graphene oxide, aniline and lead acetate used is 1:5-20:6-10; (ii) separating the graphene/lead composite hydrogel in the reaction product, washing with absolute ethanol and deionized water, subjecting to condensation treatment and freeze-drying to obtain a reduced graphene oxide/lead oxide composite aerogel; and (iii) calcining the reduced graphene oxide/lead oxide composite material aerogel under the protection of argon. USE - The material is useful for lead-carbon battery. ADVANTAGE - The material avoids the carbon floating phenomenon that occurs in the process of graphene agglomeration and mixing, greatly improves the dispersion uniformity of carbon materials in the negative plate of lead-carbon batteries, reduces the amount of hydrogen evolution during the battery charging process, and avoids the shortening of battery life caused by the drying of the electrolyte. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for use method of the composite material.
