Different morphological structures of tin sulfide (SnS2) were prepared by a solvothermal process using the thioacetamide as a sulphuring agent, are explored as anode material for Na-ion battery. All of the as-prepared SnS2 show much higher Na storage capacity and better cyclability along with good rate capability. Particularly, the flowerlike SnS2 (F-SnS2) demonstrates the highest reversible discharge capacity of 430 mAh g–1 at 50 mA g–1 and better cyclability with 97.8 % coulombic efficiency (CE) after 50 cycles. This behaviour is mainly attributed to the unique hierarchical structure and high porosity, which can provide enough space to buffer the volume expansions during the cyclic processes, increase the contact area between the electrode and electrolyte, and reduce the transport lengths of both sodium ions and electrons. The high capacity at high current rate and long cycling makes this porous F-SnS2 a promising anode material for Na-ion batteries.
