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.

Abstract: The present invention relates to an electrolyte containing a polydopamine and a lithium-sulfur battery including the same and, more particularly, to a technique in which polydopamine contained in an electrolyte adsorbs a lithium polysulfide eluted from a positive electrode of a lithium-sulfur battery. When using an electrolyte, according to the present invention, to which polydopamine particles are added, the polydopamine particles dispersed in the electrolyte act to adsorb lithium polysulfide eluted from a positive electrode during the charging and discharging, and thus can suppress the diffusion thereof, i.e., suppress a shuttle reaction, thereby improving the capacity and lifetime characteristics of the lithium-sulfur battery.
