Se-Regulated MnS Porous Nanocubes Encapsulated in Carbon Nanofibers as High-Performance Anode for Sodium-Ion Batteries

Caption

  • We have developed an efficient and scalable strategy to prepare a single-phase ternary MnS0.5Se0.5-carbon nanofiber composite with a defect-rich microstructure.
  • The Na+ storage mechanism of manganese-based sulfides after the incorporation of Se was thoroughly investigated, through systematic electrochemical characterization combined with theoretical calculations.
  • The MnS0.5Se0.5@N-carbon nanofiber composite, used as an anode, exhibits excellent reversible capacity, rate capability, and cycling stability in sodium-ion batteries.
