Graphene is one of the promising materials in lithium-sulfur batteries as cathode material, but is somewhat limited to confine sulfur owing to its 2D-structure. Molybdenum disulfide (MoS2) can be used to overcome this limits. Molybdenum disulfide (MoS2) prevented the dissolution of lithium polysulfides into the electrolyte and enhanced the conductivity of the sulfide electrode. They are also adjustable their pore size and shape with simple process. In addition to this promising material, the introduction of conductive graphene oxide could provide Li ion pathways. In this study, a facile process was used to synthesize MoS2/graphene nanosheets (GNS) composites by one-step in situ solution-phase method. In order to prove these results, electrochemical properties were characterized by cyclic voltammetry experiment between MoS2/GNS cells and only GNS cells. |
