Hollow Sn-Co nanospheres have been fabricated by galvanic replacement reaction. In particular, the hollow resultants with different shell thickness and void space can be obtained using sacrificial templates with different sizes. The structural evolution of Sn-Co hollow microspheres and structure changes during charge/discharge process were studied using XRD, SEM, and TEM. As an anodic material,...
We demonstrate the large-area synthesis of Ni 3 Si 2 -supported Si (Ni 3 Si 2 –Si) nanowires on the surface of a Ni foam via a simple and rich-yield chemical vapor deposition and subsequent rf-sputtering method. When used as an anode of Li-ion batteries, the Ni 3 Si 2 –Si nanowires show a high reversible capacity of ~1800 and ~1600mAhg −1 at...
