In order to design anode materials for sodium ion batteries with high capacity and cyclic stability, ordered flower-like SnSe was synthesized in this paper. The ordered flower-like SnSe0.5S0.5@N-C composite material was obtained by nitrogen and carbon doping on its surface and further vulcanization. The ordered flower-like SnSe0.5S0.5@N-C composite material was used as the anode of sodium ion batteries for performance testing, the structure and morphology of the composites were characterized by SEM, TEM, XRD and XPS. The results show that SnSe0.5S0.5@N-C exhibits high reversible capacity and excellent cycling performance, when used as the negative electrode of sodium ion battery. The initial discharge capacity of the composite is 746 mA·h/g at the current density of 0.2 A/g, and the reversible specific capacity is still up to 430.7 mA·h/g after 100 cycles.
