NOVELTY - Preparation method of lead-graphene composite negative electrode lead paste, involves(1) heating graphene, sodium hydroxide and metallic lead in same container until the sodium hydroxide and the metallic lead are molten, and fully mixing to obtain a liquid mixture of the metallic lead and the graphene,(2) casting the liquid mixture to obtain a lead graphene lead ingot; and (3) preparing negative lead plaster by using the lead graphene lead ingot. USE - Preparation method of lead-graphene composite negative electrode lead paste used for battery. ADVANTAGE - The sodium hydroxide is convenient to recover, the sodium hydroxide can be recycled, and production cost is reduced. The method can improve performance of battery.
