Solvothermal Synthesis of Mesoporous Manganese Sulfide Nanoparticles Supported on Nitrogen and Sulfur Co-doped Graphene with Superior Lithium Storage Performance

With the aim of enhanced cyclic stability and rate capability for lithium storage of MnS-based anode materials, a composite consisting of mesoporous MnS nanoparticles and nitrogen and sulfur co-doped graphene (NS-G/MnS) can be synthesized by a facile one-pot solvothermal procedure with thiourea as the single nitrogen and sulfur precursor. The resultant composite serves as an active anode material for lithium-ion batteries (LIBs) and exhibits a large specific capacity, good rate capability, and excellent cyclic stability. The superior lithium storage property can be ascribed to the synergistic effect between the NS-G nanosheets and mesoporous MnS nanoparticles. The NS-G/MnS composite with superior lithium storage properties can be considered as a promising candidate for high-performance LIB anodes.
