Surfactant‐Free Aqueous Synthesis of Pure Single‐Crystalline SnSe Nanosheet Clusters as Anode for High Energy‐ and Power‐Density Sodium‐Ion Batteries

SnSe with 3D hierarchical nanostructure composed of interconnected single‐crystal SnSe nanosheets is synthesized via a fast and effective strategy. Unexpectedly, when used as the anode material for Na‐ion batteries (NIBs), the SnSe exhibits a high capacity (738 mA h g−1), superior rate capability (4...

Summary:SnSe with 3D hierarchical nanostructure composed of interconnected single‐crystal SnSe nanosheets is synthesized via a fast and effective strategy. Unexpectedly, when used as the anode material for Na‐ion batteries (NIBs), the SnSe exhibits a high capacity (738 mA h g−1), superior rate capability (40 A g−1), and high energy density in a full cell. These results provide the possibility of SnSe use as NIBs anodes.
