Graphene is one of the promising materials in lithium-sulfur batteries as cathode material. Due to intrinsic high conductivity and excellent stiffness, graphene attributes to improve electrical performance of lithium-sulfur cell. Also one of the promising Q2D material, Molybdenum disulfide (MoS2) prevented the dissolution of lithium polysulfides into the electrolyte and enhanced the conductivity of the sulfide electrode. 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. Electrochmical properties were conducted by making coin cell and characterized by cyclic voltammetry in 1M LiTFSI electrolyte. |
