Synthesis of SnS nanoparticle-modified MXene (Ti3C2Tx) composites for enhanced sodium storage

SnS nanoparticle-modified Ti3C2Tx MXene composites were synthesized via hydrothermal and annealing methods and used as anode for sodium-ion batteries. The SnS nanoparticles are homogeneously dispersed between the MXene sheets, forming a unique sandwich structure. SnS/Ti3C2Tx nanocomposites electrode delivers a high reversible capacity of 412.8 mAh g−1 at 100 mA g−1. In addition, the prepared SnS/Ti3C2Tx composites possess good rate performance with a capacity of 255.9 mAh g−1 at 1000 mA g1. •SnS/Ti3C2Tx composites were synthesized by facile method.•It's the first time used as anode for sodium -ion batteries.•It exhibits enhanced reversible capacity and good rate performance.•The enhanced performance is ascribed to unique structure of SnS/Ti3C2Tx.
