One-pot synthesis of nitrogen and sulfur co-doped graphene supported MoS2 as high performance anode materials for lithium-ion batteries

• Nitrogen and sulfur co-doped graphene supported MoS2 nanosheets were successfully prepared and used as anode materials for Li-ion batteries.
• The as-prepared anode materials show excellent stability in Li-ion batteries.
• The materials show high reversible capacity for lithium ion batteries.

Nitrogen and sulfur co-doped graphene supported MoS2 (MoS2/NS-G) nanosheets were prepared through a one-pot thermal annealing method. The as prepared samples were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), Raman spectra and electrochemical techniques. The MoS2/NS-G shows high reversible capacity about 1200 mAh/g at current density of 150 mA/g and excellent stability in Li-ion batteries. It was demonstrated the co-doping of graphene by N and S could significantly enhance the durability of MoS2 as anode materials for Li-ion batteries.
