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...
