| Research Abstract |
Layers of Cu-Sn intermetallic compounds were formed by cathodic elec-trochemical alloying of electroless Cu layers with Sn using an ionic liqui bath containing Sn2+ ions at 150°C. The technique is called "reduction-diffusion(RD)" and the intermetallics formed(i. e. Cu6Sn5 and Cu3Sn) were dependent on the alloying potential. In the present work, we investigated the perfor-mance of the Cu6Sn5 layer as an anode of Li-ion battery. The formation of brass(Cu-Zn alloy) layers was also examined and it was found that Cu-Zn phases, i. e. y-Cu5Zn8, 13'-CuZn, and/or a-Cu(Zn), which define the color of the layers, were dependent on applied potential during the alloying.
