A cryodesiccation and thermal chemical approach has been used to produce FeSb₂@C composites. An interconnected mesh structure of the FeSb₂@C composite formed after the removal of the KCl by-product with simple washing. The sodium storage performance of the FeSb₂@C composite as an anode active material has been studied. After 200 cycles, FeSb₂@C delivered 283.4 mAh/g capacity with a retention of 99.1% capacity. It also showed a rate capability of 247.8 mA/g at 1000 mA/g.
