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.
