▎ 摘  要

NOVELTY - The method involves adding the bonding agent and curing agent to the carbon nanotube dispersion of the graphene oxide which is modified by the surfactant. The bonding agent and curing agent are mixed and dispersed to obtain the precursor solution. The solution is evaporated in the precursor solution. A curing treatment is performed to obtain the graphene carbon nanotube composite precursor powder. The carbonization and reduction of the graphene carbon nanotube composite precursor powder is performed to obtain a three-dimensional composite conductive framework of graphene carbon nanotubes. USE - Preparation method of graphene carbon nanotube composite conductive framework for lithium sulfur battery. ADVANTAGE - The improved method has simple structure, has high efficiency, is obtained at low cost, is easy for industrial amplification, maintains the single layer dispersion structure of graphene, generates good synergistic effect between the graphite and carbon nano tube and is a highly-efficient three-dimensional conductive framework. DESCRIPTION OF DRAWING(S) - The drawing shows a graphical diagram of a comparison chart of the powder resistivity of the graphene carbon nanotube three-dimensional composite conductive framework and carbon nanotube powder.
