▎ 摘　　要

NOVELTY - The preparation of graphene/lead compound composite material involves mixing lead compound and graphene oxide, hydrothermally reacting and ball milling to obtain graphene oxide/lead compound, using graphene oxide/lead compound material as electrode material additive to assemble the lead acid battery, and carrying out electrochemical reduction. USE - Preparation of graphene/lead compound composite material used for lead-acid battery (claimed). ADVANTAGE - The method enables preparation of graphene/lead compound composite material, avoids agglomeration of graphene to achieve a uniform dispersion of graphene and lead compound, achieves uniform mixing, and improves the battery charge acceptance capacity and cycle life. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for lead-acid battery.
