• adsorption of polysulfides [23][24]. However, the low conductivity of MoS2 often results in incomplete conversion of polysulfides. Thus, MoS2 is usually combined with carbon materials and annealing treatment is also considered [25][26]. Hence, double modification of defect-rich MoS2 nanosheets with amorphous

• fabricated via double modification of MoS2 with rGO and amorphous carbon layers. The subsequent annealing at 600 °C enhances the synergistic effect between MoS2 and rGO and amorphous carbon and further improves the capability of polysulfide conversion. This also provides an idea for designing other
