摘要

Tin monosulphide is synthesized by a simple wet chemical synthesis approach. The as-prepared tin monosulphide has been used as anode in Na-ion battery without any in situ conductive carbon or graphene coating, and the electrode exhibits a high reversible sodium reversible capacity of similar to 500 mA h g(-1) at a discharge rate of 125 mA g(-1). It also demonstrates excellent high rate performance (i.e. 390 and 300 mA h g(-1) at 500 and 1000 mA g(-1) current density respectively) and cycle stability without the addition of any expensive additive stabilizer, such as fluoroethylene carbonate (FEC), in comparison to those in current literature.
