▎ 摘　　要

NOVELTY - Lead/graphene composite material comprises lead particle electrochemically deposited on graphene sheet surface to form composite material having graphene content of 10-90 wt.%. Each graphene sheet comprises 1-50C atom layer. The lead particle has grain diameter of 100 nm to 10 mm. USE - Lead/graphene composite material used as cathode of lead-acid storage battery or as super battery negative lead carbon additive. ADVANTAGE - The lead/graphene composite material improves battery charge acceptance and high-rate partial-state-of-charge (HRPSoC) cycle life.
