Abstract | The invention discloses a method for preparing a graphene carbon nanotube composite conductive framework for a lithium-sulfur battery. The method comprises the following steps: S1, preparing mixed slurry from graphene oxide and carbon nanotue powder; S2, adding a surfactant, mixing, and dispersing so as to obtain a graphene oxide carbon nanotube dispersant; S3, adding an adhesive and a curing agent, mixing, and dispersing so as to obtain a precursor solution; S4, evaporating the solution of the precursor solution, and performing curing treatment so as to obtain graphene oxide carbon nanotube composite precursor powder; and S5, performing high-temperature carbonization reduction, thereby obtaining a graphene oxide carbon nanotube three-dimensional composite conductive framework. The methodis simple and efficient in process step, low in cost and easy in industrial application, the microstructure carbon nanotubes of the prepared graphene oxide carbon nanotube composite powder are dispersed on the surface of grap |
