▎ 摘　　要

NOVELTY - Graphene/lead compound composite material preparation involves mixing lead compound and graphite oxide in a ball-mill to get graphite oxide-lead compound composite material. The obtained graphite oxide-lead compound composite material is reduced in an inert protective gas atmosphere to form the finished composite material. USE - Method for preparing graphene/lead compound composite material (claimed) for use in lead-acid battery. ADVANTAGE - The method prepares graphene/lead compound composite material with remarkably increases charging capacity and high rates in a partial-state-of-charge condition life of battery. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic flowchart of the graphene/lead compound composite material preparation method. (Drawing includes non-English language text).
