A scale-upable MnS nanocrystal decorated N/S codoped graphene nanocomposite (MNSG) for Li-S batteries has been readily synthesized through hydrothermal process and followed by thermal treatment under N-2. Sulfur is loaded into nanohybrid to produce an outstanding Li-S battery cathode through integrating the advantages and avoiding the disadvantages of graphene and MnS. The optimized cathode can deliver a higher capacity of 756 m Ah g(-1) at 0.5 C (1 C = 1675 mAg(-1) ) after 200 cycles and can retain 73% of the initial capacity, which indicates a potential applicable cathode material for lithium-sulfur batteries.
