title: Sn-MoS2-C@C Microspheres as a Sodium-Ion Battery Anode Material with High Capacity and Long Cycle Life.
abstract: Sodium ion batteries (SIBs) have been regarded as a prime candidate for large-scale energy storage, and developing high performance anode materials is one of the main challenges for advanced SIBs. Novel structured Sn-MoS2-C@C microspheres, in which Sn nanoparticles are evenly embedded in MoS2nanosheets and a thin carbon film is homogenously engineered over the microspheres, have been fabricated by the hydrothermal method. The Sn-MoS2-C@C microspheres demonstrate an excellent Na-storage performance as an anode of SIBs and deliver a high reversible charge capacity (580.3 mAh g-1at 0.05 Ag-1) and rate capacity (580.3, 373, 326, 285.2, and 181.9 mAh g-1at 0.05, 0.5, 1, 2, and 5 Ag-1, respectively). A high charge specific capacity of 245 mAh g-1can still be achieved after 2750 cycles at 2 Ag-1, indicating an outstanding cycling performance. The high capacity and long-term stability make Sn-MoS2-C@C composite a very promising anode material for SIBs.
