Thin Film Nanostructured ATO and ATO Based Composite Anodes for Li-Ion Batteries

Abstract

In this study, antimony doped tin oxide lms were deposited on multiwall carbon nanotube buckypaper and Cr coated stainless steel substrates using a radio frequency magnetron sputtering process in a mixed oxygen/argon (5/95) gas environment. The depositions of antimony doped tin oxide on the multiwall carbon nanotube buckypaper and stainless steel substrates were carried out using the parameters organized as: target composition antimony doped tin oxide (SnO2:Sb = 90:10 wt%); total system pressure 1 Pa; sputtering power (RF) 100 W. The surface morphology of the antimony doped tin oxide lms was investigated by eld emission scanning electron microscopy. The crystallographic structure of the samples was determined by X-ray diraction. The electrochemical properties of antimony doped tin oxide and antimony doped tin oxidemultiwall carbon nanotube nanocomposite anodes containing CR2016 cells were measured by galvanostatic chargedischarge experiments.
