Abstract
The present invention relates to a self-assembled composite of carbon nitride and graphene oxide, and in particular, to including a self-assembled composite prepared by heat treating a mixed solution dissolving melamine, tri-thiocyanuric acid and graphene oxide (GO) in a positive electrode of a lithium-sulfur battery to suppress elution of lithium polysulfide. According to the present invention, the self-assembled composite containing a pyridinic group in large quantities and having improved conductivity adsorbs lithium polysulfide eluted from a positive electrode during charge and discharge and performs a role of preventing diffusion of the lithium polysulfide, and therefore, lithium-sulfur battery capacity and lifecycle properties can be enhanced by suppressing a shuttle reaction.
