Binder Free SnO 2 -CNT Composite as Anode Material for Li-Ion Battery

Tin dioxide-carbon nanotube (SnO 2 -CNT) composite films were synthesized on copper substrates by a one-step process using hot filament chemical vapor deposition (HFCVD) with methane gas (CH 4 ) as the carbon source. The composite structural properties enhance the surface-to-volume ratio of SnO 2 de...

Summary:Tin dioxide-carbon nanotube (SnO 2 -CNT) composite films were synthesized on copper substrates by a one-step process using hot filament chemical vapor deposition (HFCVD) with methane gas (CH 4 ) as the carbon source. The composite structural properties enhance the surface-to-volume ratio of SnO 2 demonstrating a desirable electrochemical performance for a lithium-ion battery anode. The SnO 2 and CNT interactions were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Raman spectroscopy, X-ray photoelectron spectroscopy (XPS), and Fourier transform infrared-attenuated total reflectance (ATR-FTIR) spectroscopy. Comprehensive analysis of the structural, chemical, and electrochemical properties reveals that the material consists of self-assembled and highly dispersed SnO 2 nanoparticles in CNT matrix. The process employed to develop this SnO 2 -CNT composite film presents a cost effective and facile way to develop anode materials for Li-ion battery technology.
