The three-dimensional porous Fe–Sb–P amorphous alloy electrodes were prepared by electroplating on porous copper current collector. The structure and electrochemical performance of the electroplated Fe–Sb–P amorphous alloy electrodes have been investigated in detail. XRD results showed that the as-deposited Fe–Sb–P alloy electrode exhibits an amorphous nature. Electrochemical tests indicated that at the 50th cycle, the Fe–Sb–P amorphous alloy electrodes can deliver a discharge capacity of 448 mAh g −1. The porous and amorphous structure of electrode of Fe–Sb–P alloy was beneficial in relaxing the volume expansion during cycling, which improved the cycle ability of Fe–Sb–P alloy electrode.
