▎ 摘　　要

NOVELTY - The method for preparing graphene/carbon nanotube composite conductive agent, involves mixing graphene powder with metal salt solution, drying and placing in an oxygen-containing atmosphere for calcinations to obtain graphene oxide intercalated powder, placing the powder in a reducing atmosphere to obtain graphene powder intercalated with metal particles, mixing the graphene powder intercalated with the metal particles with volatile organic compound, calcining at 600-900°C, and placing at 1400-1800°C for heat preservation, mixing and dispersing the graphene or carbon nanotube composite powder, dispersing agent and solvent to obtain the product. USE - Method for preparing graphene/carbon nanotube composite conductive agent used in preparing batteries (all claimed). ADVANTAGE - The method is simple, suitable for mass production, and provides graphene/carbon nano-tube composite conductive agent with low resistivity.
