摘要

The effects of electrodeposition conditions on the cycle performance of Sn electrodes wereinvestigated in this study. Sn electrodes were electrodeposited on Cu substrates under differentconditions, such as the electrodeposition baths and the current densities to maximize cycleperformance and coulombic efficiency. By using different types of electrodeposition baths, Snelectrodes with different phases were electrodeposited. The formation of an Cu6Sn5 phase betweenthe Sn layer and Cu substrate contributes to the improvement of the cycle performance of the Snelectrode. As the current density increased, the Sn layers became less dense structure with nodule-typemorphology. The less dense Sn electrodes with nodule-type morphology exhibited a better cycleperformance due to the absence of the high-voltage irreversible reaction and their buffering effects forvolume expansion.
