MoS₂@rGO Nanoflakes as High Performance Anode Materials in Sodium Ion Batteries

A simple one-pot hydrothermal method is developed for fabrication of MoS₂@rGO nanoflakes using the economical MoO₃ as the molybdenum source. Benefiting from the unique nanoarchitecture, high MoS₂ loading (90.3 wt%) and the expanded interlayer spacing, the as-prepared MoS₂@rGO nanoflakes exhibit greatly enhanced sodium storage performances including a high reversible specific capacity of 441 mAh g^-1 at a current density of 0.2 A g^-1, high rate capability, and excellent capacity retention of 93.2% after 300 cycles.
