Edge-Oriented SnS2 Nanosheet Arrays on Carbon Paper as Advanced Binder-Free Anodes for Li-Ion and Na-Ion Batteries

Abstract

Two-dimensional SnS2 material is promising for energy storage, but the specific capacity and cycling performance are still far from satisfactory. Herein, a rational design of edge-oriented SnS2 nanosheet arrays with vertical alignment on a carbon paper for Li-ion and Na-ion batteries is reported. The unique hybrid architecture provides sufficient electrode/electrolyte interaction area, fast electron/ion transport and efficient volume accommodation, thereby enabling high and stable electrochemical utilization as well as fast reaction kinetics of SnS2. The as-prepared SnS2@C hybrid paper, when used as binder-free anodes for both Li-ion and Na-ion batteries, exhibits high specific capacity, superior rate capability and excellent cycling durability. The outstanding electrochemical performance suggests that the SnS2 nanosheet arrays with preferential edge orientation hold great potential serving as advanced anode materials for the use in energy storage applications.
