Abstract

In our previous work, an amorphous Sn-CoSn-Co alloy film prepared by electrocodeposition on Cu foil with rough surface was found to transform to a new phase structure during charge-discharge cycle to show more stable reaction with lithium. In this work, we prepared Sn-CoSn-Co film on copper current collector which originally included the new phase structure, and examined its electrochemical and structural properties by scanning electron microscopy, transmission electron microscopy, X-ray diffraction, extended X-ray absorption fine structure, and magnetic susceptibility measurement. Influence of the phase transformation on the cyclability is discussed in terms of adhesion between the film and current collector.
