| In this work, tin oxide (SnO2) films were deposited on multiwall carbon nanotube buckypaper using a rf magnetron sputter process in a mixed oxygen/argon (1/9) gas environment. Conditions for the growth of SnO2 thin films on multiwall carbon nanotube buckypaper by rf sputtering are: target composition SnO2 (99.999 wt%); Total system pressure 1 Pa; Sputtering power (rf) 75, 100 and 125 W, respectively; O2/Ar (1/9) gas mixture. The surface morphology of the SnO2 multiwall carbon nanotube composite films was investigated by scanning electron microscopy. The crystallographic structure of the sample was determined by X-ray diffraction. The electrochemical properties of SnO2 multiwall carbon nanotube composite anodes were investigated by galvanostatic charge-discharge experiments. |
