Abstract
Sn–Co alloys were electrodeposited on the rough Cu foil and smooth Cu sheet, respectively. The capacity retention of the Sn–Co alloy electrode electrodeposited on the rough Cu foil in the 70th cycle was found to be 80.0% compared with the maximal capacity, which was much better than that of the Sn–Co alloy electrode on the smooth Cu sheet. The revolution of the surface morphology of the Sn–Co alloy electrode during cycling was investigated by scanning electron microscopy. The result indicated that the reversibility of the expansion and contraction of the Sn–Co alloy electrode on the rough Cu foil during charging/discharging assisted by the unique rough surface was one main reason of improving the cycleability. Solid electrolyte interphase (SEI) film was detected on the Sn–Co alloy electrode surface by electrochemical impedance spectroscopy (EIS) during lithiation/delithiation, and the result demonstrated that the SEI film suffered breaking and repairing at different lithiation status. In addition, the unique phase transformation process for the Sn–Co alloy electrode during first lithiation was also investigated by EIS.
