| Popis: | Cu–Sn alloy foam is a promising electrode material for Li-ion batteries. In this study, Cu–Sn alloy foam was produced by diffusion-limited electrodeposition in alkaline electrolyte using polyurethane (PU) foam template. Our major concern is to form Cu–Sn alloy foam with nanocrystalline surface morphology by adjusting electrodeposition conditions such as deposition potential and metal ion concentration. Cu–Sn alloy layers comprising of nanoclusters such as nanospheres, nanoellipsoids, and nanoflakes were created depending on electrodeposition conditions. Larger surface area of nanocluster-interconnected Cu–Sn alloy layer was created when both Sn concentration and negative deposition potential were higher. After decomposing PU template thermally, Cu–Sn alloy foam of Cu, Cu6Sn5, and Cu3Sn phases was finally produced. |
