Excellent electrochemical performance of tin monosulphide (SnS) as a sodium-ion battery anode

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 ∼500 mA h g −1...

Zusammenfassung: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 ∼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.
