▎ 摘　　要

NOVELTY - Lead sulfide-graphene composite electrode material, is claimed. The lead sulfide-graphene composite electrode material is a graphene intercalated lead sulfide composite material. USE - The lead sulfide-graphene composite electrode material is useful in cathode lead paste for lead-acid battery (claimed). ADVANTAGE - The lead sulfide graphene composite electrode material produces cathode lead paste for lead-acid battery, which has long cycle life and stability. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: Preparation of lead sulfide-graphene composite electrode material. The method uses organic carbon source and organic sulfur; Cathode lead paste for lead-acid battery, comprising 80-100 pts. wt. lead powder, 5-10 pts. wt. lead sulfide-graphene composite electrode material, 1-3 pts. wt. carbon nanotubes, 1-3 pts. wt. barium sulfate, 0.1-0.5 pts. wt. polyester staple fiber, 3-10 pts. wt. sulfuric acid and 5-15 pts. wt. water; Preparation of cathode lead paste for lead-acid battery.
