摘要

Metal dichalcognide SnS2 have been demonstrated a potential candidate for sodium-ion batteries (SIBs) anode due to its high theoretical specific capacity and large interlayer spacing. However, the issues of sluggish kinetics and large volume change associated with the conversion and alloying reaction need to be addressed prior to the practical application. Herein, mesoporous composite of SnS2 nanosheets crosslinked by bacterial cellulose-derived carbon nanofibers (SnS2/BC-CNIFs) has been fabricated by hydrothermal method, which displayed superior rate capability and cycling stability. The nanocomposite of SnS2/BC-CNIFs-5 (Specific surface is 144.7 m(2) g(-1)) delivered a high specific capacity of 408 mAh g(-1) at 50 mA g(-1) after 100 cycles and 196.4 mAh g(-1) at a high rate of 2 A g(-1).( ) The enhanced Na storage properties of SnS2/BC-CNIFs may due to the rational design of SnS2 nanosheets interconnected by conductive carbon nanofibers, which facilitated the ion and electron transport throughout the electrode.
