Abstract

The present paper focuses on a nanostructured SnCo alloy electrochemically prepared bytemplate method in view of its use as anode material alternative to graphite in lithium-ion batteries.The fabrication of SnCo nanowire arrays was carried out by potentiostatic co-deposition of the twometals by using nanostructured anodic alumina membranes as template. Electrochemical tests onlithiation-delithiation of these SnCo electrodes in conventional organic electrolyte (EC:DMCLiPF6) at 30°C showed that their specific capacity was stable for about the first 12 cycles at a valuenear to the theoretical one for Li22Sn5 and, hence, progressively decayed.
