| Abstract: | A simple chemical vapor deposition method has been developed to synthesize nickel silicide nanowire arrays with different diameters on Ni foils,which are characterized by X-ray diffractometry(XRD) and field emission scanning electron microscopy(FESEM) and high-resolution transmission electron microscopy(HRTEM).Furthermore,the discharge capacity of lithium-ion batteries by using the arrays as anode was studied.It is indicated that the nickel silicide nanowire arrays show good cycling performance,indicating t... |
