Opis:
In this study, tin oxide (SnO₂) coatings on Cr coated stainless steel and multi-walled carbon nanotube (MWCNT)/graphene substrates were prepared using a radio frequency magnetron sputtering process as anode materials in lithium-ion batteries. SnO₂ thin film and SnO₂/MWCNT/graphene composite were characterized with field-emission scanning electron microscopy, X-ray diffraction, and electrochemical tests (cyclic voltammetry and galvanostatic cycling). The electrochemical properties of SnO₂ and SnO₂/MWCNT/graphene composite anodes were studied using 2016-type coin cells assembled in an argon-filled glove box. The cells were cyclically tested on a MTI BST8-MA battery analyzer. The cyclic voltammograms of SnO₂ anode and SnO₂/MWCNT/graphene composite anode were obtained over the potential range of 0.05-3.0 V and 0.05-2.5 V at a scan rate of 0.05 mV s¯¹, respectively.

Opis:
In this study, antimony doped tin oxide films 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 ($SnO_2$:Sb = 90:10 wt%); total system pressure 1 Pa; sputtering power (RF) 100 W. The surface morphology of the antimony doped tin oxide films was investigated by field emission scanning electron microscopy. The crystallographic structure of the samples was determined by X-ray diffraction. The electrochemical properties of antimony doped tin oxide and antimony doped tin oxide-multiwall carbon nanotube nanocomposite anodes containing CR2016 cells were measured by galvanostatic charge-discharge experiments.

Opis:
In this study, the reversible capacities, as well as the cycling behavior, of crystalline antimony-doped tin oxide (ATO) films have been investigated. ATO films were deposited on Cr-coated stainless steel substrates by the RF magnetron sputtering technique, with antimony-doped tin oxide (SnO₂:Sb) target in a mixed oxygen/argon gas environment. The ATO films were deposited for 1.0 h in a mixture of Ar and O₂ environment with O₂/Ar ratio of 10/90, at sputtering power of 75 W, 100 W and 125 W RF. ATO films were examined by X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM). The electrochemical properties of ATO anodes were studied using 2016-type coin cells assembled in an argon-filled glove box.
