Amorphous ATO and amorphous ATO based composite anodes for Li-ion batteries

In this study, amorphous antimony doped tin oxide (ATO) coatings on Cr coated stainless steel and multiwall carbon nanotube (MWCNT) buckypaper substrates were prepared using a radio frequency (RF) magnetron sputtering process as anode materials in lithium-ion batteries. The MWCNT anode, amorphous SnO2:Sb anode and amorphous SnO2:Sb-MWCNT nanocomposite anode have shown first discharge capacities of 446 mA h g−1, 1064 mA h g−1 and 1462 mA h g−1, respectively. The best cycling performance were observed for amorphous SnO2:Sb-MWCNT nanocomposite anode.
