Abstract:

Li4Ti4.92(CrV)(0.04)O-12/C composites were synthesized at 800 degrees C under a flow of argon/acetylene gas mixture taken in the 40:1 volumetric ratio. X-ray diffraction (XRD), thermogravimetric analysis (TGA), magnetic susceptibility, Raman spectroscopy, and electron microscopy (TEM) were used to characterize the phase structure, composition, and morphology of the composites. Transmission electron microscopy and Raman spectroscopy confirmed that carbon exists on the surface of the spinel matrix. The composites proved to have a modified structure in comparison with the pristine spinel phase. (C) 2011 Elsevier Masson SAS. All rights reserved.
